[Bug 527875] Re: libvirt0 unable to operate due to missing essential files

[IAN DELANEY]

ok, you're going to hate me for this, I know it.  As if I've not input enough.  I did do a separate install of karmic,
and I reproduced this state.  I installed a 64 version.

I installed, prepared the kernel for karmic.  Unless I missed it, Ubuntu
didn't provide a xen kernel for karmic.  I provided my own, and it's run
lenny 64, karmic 32, now karmic 64, gentoo 32 and gentoo 64.  It may not
be perfect.  Anyway, having booted into xen.

More of the same.  Installed virt-manager, try connecting to xen by gui,

Unable to open connection to hypervisor URI 'xen:///':

I booted into the freshly installed server kernel, and

Sorry, try again.

Those elusive sockets libvirt-sock  libvirt-sock-ro are there, in an
environment absent of xen.

Yes well, I fear this may lead nowhere if you can't reproduce.  What
kernel would you use??
