virtual machines freeze on boot

[Barry Warsaw]

Binary package hint: virt-manager

This may be a bug in libvirt or kernel, but for now I'm reporting it here because I start my virtual machines in virt-manager.

With today's Lucid beta updates, none of my virtual machines will boot. I have three vms that have been working beautifully in Lucid until now. Two are Lucid guests and one is a Karmic guest. Host is Lucid running 2.6.32-19-generic x86-64. One vm freezes after "Booting from Hard Disk..." message on the console. Another gets to "GRUB loading." a third simply hangs right off the bat.

I start virt-manager with:

virt-manager -c qemu:///system

It's probably not a kernel bug since I just rebooted the host to my last known good kernel 2.6.32-18-generic and the vms will still not boot.

Host kernel: Linux begallew1 2.6.32-21-server #32-Ubuntu SMP Fri Apr 16 09:17:34 UTC 2010 x86_64 GNU/Linux
Guest OS: Solaris 10 and Ubuntu 10.04.
lsb_release: lucid

The Solaris VM ran fine under karmic. Since doing a do-release-upgrade on the host, all VMs (Solaris 10 and a freshly built 10.004) hang after the "Grub loading stage 2" message.

Booting from CD images works just fine.

My host doesn't have hardware support for virtualization, so I believe this is unrelated to 559896.
