KVM Guest installed from console. But how to get to the guest's console?
- by badbishop
I'm trying to install a fully virtualized guest (Fedora 14 x86_64) on KVM (RHEL 6), using command-line only (both hypervisor and guest). It goes without errors, and without a tangible result . I'd like to know how to do a text-only installation.
So, here's what I've done:
# virt-install \
--name=FE --ram=756 --vcpus=1 \
--file=/var/lib/libvirt/images/FE.img --network bridge:br0 \
--nographics --os-type=linux \
--extra-args='console=tty0' -v \
--cdrom=/media/usb/Fedora-14-x86_64-Live-Desktop.iso
Starting install...
Creating domain... | 0 B 00:00
Connected to domain FE
Escape character is ^]

Now what? As I understand after googling for a couple of days, I should see the guest's output from the text installation, but nothing happens. virt-viewer cannot connect to it, kindly suggesting that I explore all the options by adding --help (which I did). If I reconnect with virsh, I see this:
Domain installation still in progress. You can reconnect to
the console to complete the installation process.

This shows that VM is running

I'm obviously missing something that many others don't, but what is it? Thanx in advance!
