virtualisation with kvm: export services from guest to the host
- by ascobol
Hello,
I would like to export some services from the guest os to the host os, via kvm, and by the same way learn some things about networking.
I have tried the following commands:
In the host (kubuntu 10.4):
$ sudo tunctl -u ascobol
Set 'tap0' persistent and owned by uid 2401
$ sudo ifconfig tap0 192.168.2.1 netmask 255.255.255.0 broadcast 192.168.2.255
The ifconfig command returns:
$ /sbin/ifconfig
tap0 Link encap:Ethernet HWaddr 3e:4e:e3:cc:bc:92
inet addr:192.168.2.1 Bcast:192.168.2.255 Mask:255.255.255.0
inet6 addr: fe80::3c4e:e3ff:fecc:bc92/64 Scope:Link

192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 tap0
Then I run the virtual machine (ubuntu server 10.4):
$ sudo kvm -hda ubuntuserver104.qcow2 -net nic -net tap,name=tap0,script=no
(I'm using sudo because without it fails with the following message:)
warning: could not configure /dev/net/tun: no virtual network emulation
With sudo the virtual machine boots, I just get this message:
pci_add_option_rom: failed to find romfile "pxe-rtl8139.bin"
In the virtual machine:
$ ifconfig eth0 192.168.2.2 netmask 255.255.255.0 broadcast 192.168.2.255
Now if I run:
$ ssh 192.168.2.2
I just get a
No route to host
What is wrong with this setup ?
Thanks !
