  • error: The specified device is claimed by another driver (uvcvideo) on the host operating system

    - by kamal
    I am trying to run an ubuntu 11, in VMplayer 5 on an ubuntu 12.04 host, and when trying to run the guest, i get this error, and no display. The specified device is claimed by another driver (uvcvideo) on the host operating system. The device might be in use. To Continue, the device will first be disconnected from its current driver. I also found a sort of related comment ( RESOLVED ) on similar issue on: ubuntu forums

  • PERC H710 mini raid controller advanced settings (BIOS)

    - by gregg
    I upgraded from a PERC h310 to an H710 controller on my Dell R620 but didnt get any increase in performance. This is a ESXi host with a 5 disk RAID 5. I noticed when going to the RAID BIOS that the advanced settings section was not activated/checked off. In that section is the strip element size: 64kb (default) read policy: no read ahead and the write policy: write-through. Will checking that section do any harm to the existing raid array or will it simply enable those policies and hopefully boost performance? Or, lastly, is it already using those policies and the checkmark is simply to activate them for changes

  • ESXI 4 IPMI 2.0 - Cannot connect to IPMI after boot past bios

    - by adamflavell
    Dear All, I would appreciate any help here. I have a Supermicro 6016T-NTRF running ESXI 4 fine. The health monitors are showing up so ESXI is picking up the IPMI status. But I cannot connect to the host remotely via the dedicated IPMI nic. When the machine is in bios section I CAN connect but as soon as ESXI starts to boot I get blocked. Supermicro say the issue must be that ESXI is blocking the IPMI ports. How can this be corrected? I have read that there is no firewall on ESXI 4. Thanks, Adam

  • Register a dll in Windows Server 2003

    - by Karee
    I'm trying to register some DLLs for a particular application but having some problems. The DLLs are stored in the application folder in the D: drive. I run cmd.exe, go to the D: drive and run regsvr32, but it gives me the error: "The was loaded, but the DllRegisterServer entry point was not found. This file cannot be registered." After searching for other solutions, I also tried copying the DLLs into the C:\WINDOWS\system32 folder and running regsvr32 directly there but that didn't work either. It gave me the same error. I'm not very familiar with Windows Administration, so I may need detailed instructions/explanations. Any help would be greatly appreciated! Thank you very much!

  • Hyper-V Deployment Options Best Practices

    - by Erv Walter
    In what circumstances would you choose each of the following deployment options: Hyper-V installed as the bare bones Windows Hyper-V Server 2008 R2 Hyper-V role installed on a Windows Server 2008 R2 Server Core installation Hyper-V role installed on a Windows Server 2008 R2 Full Installation For example, I know there are licensing considerations for each option: With Hyper-V on top of a full installation of Enterprise or Data Center edition, you can use Windows Server as a guest OS without needing additional licenses (4 for Enterprise, unlimited for Data Center) With "Windows Hyper-V Server" you have to obtain licenses for each guest OS. But my real question is, are there technical considerations as well? I understand that the Full Installation doesn't perform as well as the other two options, but is there a significant difference between Server Core and "Windows Hyper-V Server"? What are the pros and cons of Hyper-V on Server Core vs "Windows Hyper-V Server" and when would you choose each?

  • Problems with 2 ISCSI connections esxi 3.5

    - by rphilli5
    I am running a dell poweredge 1950 with 4 nic cards. 1 is bonded to SAN #1 on 192.168.90.xx. The second SAN is on a separate network - 192.168.7.xx The network adapter can view the ip range of the san and the NIC can be pinged from 192.168.7.xx range. vswitch1 and vswitch2 are configured identically except for the ip address. The second SAN has been added to the iscsi software adapter but the SAN is never recognized. I can connect to the SAN from other machines on the local network. Is there something else that needs to be configured for the iscsi software adapter to know which vswitch to use?

  • VMFS recovery - how do you proceed?

    - by ToreTrygg
    The more I look into ESX the more often i have to handle cases where the partition table of a disk with a VMFS volume gets corrupted. The reasons for this can be * idiot user * failed update * power failure * .... I guess you guys must already have something like a usual procedure on how to work through this cases. I am especially interested in a straight fast way to find out if the VMFS volume itself is corrupted beyond repair. So far I use very time consuming attempts with scans with Testdisk and similar tools. Do you have better / faster ways ?

  • Can I have different ESX hosts accessing the same LUN over different protocols?

    - by Kevin Kuphal
    I currently have a cluster of two ESX 3.5U2 servers connected directly via FiberChannel to a NetApp 3020 cluster. These hosts mount four VMFS LUNs for virtual machine storage. Currently these LUNs are only made available via our FiberChannel initator in the Netapp configuration If I were to add an ESXi host to the cluster for internal IT use can I: Make the same VMFS LUNs available via the iSCSI initiator on the Netapp Connect this ESXi host to those LUNs via iSCSI Do all of this while the existing two ESX hosts are connected to those LUNs via FiberChannel Does anyone have experience with this type of mixed protocol environment, specifically with Netapp?

  • SAN Replication for Fault tolerance using EVA4400

    - by Sergei
    Hi Everyone, I hope that someone would point me in the correct direction - it looks like I have no enough konwledge in the subject and timeframes are too tight for me to explore different scenarios in depth.. We have two datacenters few miles away from each other connected by 100 Mbps link.Each datacenter will have 5 BL490 blades with ESX Standard hosting about 50 VMs. Eac hsite has HP eva4400 SAN with SAN replication set up.VC is going to be in the first datacenter and both datacenter are networked. SAN Replication is block level so it seems like I cannot just replicate changes but all writes would have to be replicated.This should not be a problem as link can sustain about 1.8 TB a dayand data can be buffered. I am having trouble however visioning how recovery would work in this case.We don't need instant recovery , I would say 4 hours recovery time is accepted so fancy automatic SRM like DR scenario would not be easily accepted due to the financial reasons, however any comments are welcomed. Current idea is following: replicate LUNs from primary site to the secondary.When disaster strikes, IT personnel switches on ESX hosts on the remote side and connects replicated LUNS to them, then registers VMs and changes IP address. I understand that this seems like horribly manual process and I almost sure I have missed some obvious pitfalls here. Could someone let me know what direction should I go?An articles regarding the subject? This is a brand new setup and we would rather build up basic recovery process and scale it later.I just need to have a right direction to allow for such scalability. Thank you very much in advance!

  • Trouble with Windows 7

    - by vtimmerm
    Hi, I'm trying to virtualize an application for Windows 7 but am running into trouble: Application will run fine in Windows 7 if installed in the base. When it is virtualized, it will run on XP, but not on Windows 7. I have tried this in three ways: Captured on XP with ThinApp 4.0 Captured on XP with ThinApp 4.5 Captured on Windows 7 with ThinApp 4.5 Even when captured on Windows 7, it will not run on Windows 7 but will run on XP. When captured with a rival product, Altiris SVS, the virtualized app runs fine on Windows 7. Any idea's what could cause this behaviour? Looking at the trace file, you see that they are different right from the start when comparing Windows 7 and XP tracefiles. What could cause it to go in completely different directions? (And why does the tracefile on Windows 7 say: Operating System Unknown? Does everybody have that on Windows 7 even with 4.5?) The error message is: "Object variable or with block variable not set". Thanks, Vincent

  • Can single ESXi host make use of two separete iSCSI box?

    - by user71061
    Hi! I have problem with using multiply iSCSI targets with single ESXi host (in my case they are two FreeNAS hosts, but I suspect that this problem will occur with any two iSCSI box of that same type/model). If I configure two FreeNAS hosts as iSCSI targets (say iSCSI A and iSCSI B), then I can use both of them with my ESXi host, but only one at a time (i.e only iSCSI A or only iSCSI B, but not both of them simultaneously). If I try to add second iSCSI target to my iSCSI adapter (of course it has unique iqn name), then in a details pane of this adapter (it is iSCSI software adapter), I see that total number of paths has increased accordingly, but not total number of devices (so I can't use it as another storage). What should I do? It is impossible to attach two iSCSI targets to single adapter? I'm using free version of ESXi 4.1. Maybe it is an limitation of free version? Thanks in advance for any sugestion.

  • ESXi 5.1 ghettoVCB stuck at Clone: 10% done

    - by stormdrain
    Trying to run ghettoVCB for the first time here. I am using a NAS that is set up as a datastore on the host. I did a dry run and it completed without error. The VM is ~500GB and there is only one on the host that I'm trying to backup.

Clone: 10% done. and it's been that way for over an hour now. Stuck at Clone: 10% done.. Thing is: I can see the vmdk on the NAS. And it looks like almost the whole thing is there. On the NAS it's showing ~430GB but on vSphere Client Summary is shows as 507GB. I don't see the vmdk on the NAS growing any more. The logfile mimics some of the above and is sitting at "Creating Snapshot..." and nothing else is coming in. Is the vmdk on the NAS showing all those GB because of the provisioning or something? i.e. is the size of the file not necessarily indicative of the amount of actual data that has been copied? Is there are reason it might be "Stuck" at 10%? i.e. could it really be taking this long? Any other tips? Thanks. Edit: as soon as I hit the Submit button, I glance over to see that it has incremented to 11% done. Good to know it'll be complete sometime around when the sun explodes.

  • Storage device not found on ESX4 with AIC-9410

    - by Mads
    I am trying to install ESX 4.0 update 1 on a Supermicro X7DBR-3 system with an embedded AIC-9410 HBA (this HBA is listed on the HCG with Vendor ID 9005 and Device ID 041f) . All SATA controllers are disabled in the BIOS and the logical drive shows up in the Adaptec device summary during POST, however there is nothing listed on the Storage Device screen. The HBA itself is listed if I run esxcfg-info but not if I run esxcfg-scsidevs -a (under ESXi for that last command) Any ideas where I can look next or what might be wrong?

  • iSCSI SAN Implementation with several ESXi hosts and two Equallogic SANs

    - by Sergey
    I work for a small state college. We currently have 4 ESXi hosts (all made by Dell), 2 EqualLogic SANs (PS4000 and PS4100) and a bunch of old HP Procurve switches. The current setup is very far from being redundant and fast so we want to improve it. I read several threads but get even more confused. The Procurve Switches are 2824. I know they don't support Jumbo Frames and Flow Control at the same time, but we have plans to upgrade to something like Procurve 3500yl. Any suggestions? I heard Dell Powerconnects 6xxx are pretty good but I'm not sure how they compare to HPs. There will be a 4-port Etherchannel (Link Aggregation) between the switches, and all control modules on SAN will be connected to different switches. Is there anything that will make the setup better? Are there better switches then Procurves 3500yl that cost less than 5k? What kind of bandwidth can I expect between ESXi hosts (they will also be connected to 2824 with multiple cables) and SANs?

  • How to SSH to guest ubuntu OS in vmplayer4

    - by Grace
    I have installed vmplayer4.0.4 on Windows7, and install ubuntu12.04 as Guest OS. Basically i have two problems: Default vmplayer use NAT for network access. I could ping the guest OS from the Host OS. But how could i access the Guest OS from outside the Host OS? If i change to Bridged Mode, sure the Guest Ubuntu OS could get DHCP ip in the same subnet as Host OS. But i could not ping the Guest OS from the Host OS, or vice versa, even if i disable the iptables firewall on Ubuntu Guest OS like following: iptables -F iptables -X iptables -t nat -F iptables -t nat -X iptables -t mangle -F iptables -t mangle -X iptables -P INPUT ACCEPT iptables -P FORWARD ACCEPT iptables -P OUTPUT ACCEPT I could not figure it out, could anyone help on this issue? Thanks in advance.

  • OOM-Killer, jboss and kernel panic

    - by user32425
    Hi, We are running RedHat 3.4.6(x32) on VMWareEsx3.5(x64) with 6GB RAM. A few java processes(including jboss) are running in the background. The problem is that the java processes consume lots of memory, and sometimes they are killed by the OOM-killer. When OOM-killer is about to act, the free physical memory is very low 100MB-200MB, but the swap is not used (99% free). Sometimes this causes a kernel panic too. So why isn't the swap used? How to investigate this kernel panic? Is using 6GB memory on 32bit Redhat wise? Thanks

  • ghettoVCB issue

    - by romgo75
    I have setup a ghettoVCB script in order to backup three VM. I put it in a crontab but I have an issue. In my backup folder I have 3 different folders, one for each VM. In each folder I have the following files: -rw-r--r-- 1 root root 1263 Mar 17 01:51 vm1-2010-03-16--2.gz -rw-r--r-- 1 root root 1263 Mar 17 00:41 vm1-2010-03-16--3.gz -rw-r--r-- 1 root root 1261 Mar 18 01:22 vm1-2010-03-17--1.gz drwxr-xr-x 1 root root 980 Mar 19 23:39 vm1-2010-03-19 The problem is the last folder.

  • NAS4Free disk encryption and ZFS error

    - by MiNT
    I have installed a NAS4Free on a VM, and as recommended, i installed it on a 1GB virtual disk, and assigned another disk 500GB to this VM for file storage. I have created the disk, encrypted it, created a ZFS virtual disk, and then a ZFS storage pool. Everything was working. On every restart of this VM i needed to go on and mount the encrypted drive. Recently i upgraded the host machine, and now i cant mount or make it work. I have tried removing everything and setting up from scratch everything, with the exception of formating the disk, i have used an encrypted one without formating it. Does anybody have any suggestion on how can i at least get back my data, can i mount somehow the encrypted drive even in another utility, just need to get back the data that were on it.
