Ubuntu 8.04 LTS guest with virtio support?

[Neil Aggarwal]

Hello:

I am running KVM 83-105.el5_4.13 installed with CentOS 5.4

According to this page:
http://www.linux-kvm.org/page/Guest_Support_Status
Ubuntu 8.04 LTS guests have some issues with virtio.

When I tried to install an Ubuntu 8.04 guest with the
accelerate option to virt-install, it crashes during
the install.  I assume this is the issue with virtio.
If I install the gues without the accelerate option,
it works, but is noticeably slow.

Is it possible to install the Ubuntu guest and then
add the virtio drivers to it after the install?  
Will that be stable?

Thanks,
	Neil

Assuming the failure was due to virtio, yes. Just use ide/e1000 instead.
Getting the crash logs would be helpful.

I turned on debugging and checked 
/root/.virtinst/virt-install.log but don't
see any useful info.

Is there someplace else to look?

Thanks,

I installed the ubuntu guest without the accelerate
option.  The install was slow but worked.

After the install, I shutdown the guest and added
<model type='virtio'/> to the interfaces section of
the guest's xml definition and started it.

Everything seems to be working.

Thank you,
	Neil
