And third issue aswell:
3) Creating an HVM guest using virt-manager with file-based storage uses loopback-mount, not blktap
When I manually create a new Xen HVM guest using virt-manager, and choose file-based image for storage of the VM, it seems to be set up to use file: backend/driver with loopback-mounted image file:
<disk type='file' device='disk'>
<driver name='file'/>
<source file='/var/lib/libvirt/images/testvm2.img'/>
<backingStore/>
<target dev='hda' bus='ide'/>
</disk>
# losetup -a
/dev/loop0: [fd00]:1709109 (/var/lib/libvirt/images/testvm2.img)
With earlier versions of rpms similar setup used blktap2 backend.. (and yes, I do have blktap module loaded in dom0 kernel).
Thanks,
