[libvirt-users] 32 bit client on 32bit host

[Roland Giesler]

As mentioned in another post, I trying to set up an existing Windows7
partition on an Ubuntu desktop as a libvirt guest and now have the
following configuration files for this:

<domain type='qemu'>

  </devices>

I manually changed the
<emulator>/usr/bin/qemu-system-x86_64</emulator> to
<emulator>/usr/bin/qemu-system-i386</emulator> since my hard drive
partition contains 32bit Windows 7, although I'm not sure that this
applies.

My current machine setup it dual-boot, so I can boot Windows 7 from
the first partition (/dev/sda1) using a grub boot menu.  However, when
I start the Windows 7 VM, I just get "Booting from Hard Disk" in the
virt-manager console.

What could be the problem?

Lastly: /def/sda1 in a boot partition, but the rest of Windows is
installed on /dev/sda2, but this partition is not marked bootable.

thanks
