[Pkg-xen-devel] Bug#702428: HVM fails to start with VIF / qemu-dm error

[Daniel Pocock]

Package: xcp-xapi
Version: 1.3.2-14
Severity: important

I imported a HVM from a legacy xm environment.

It is attached to one vif, the xenapi management vif

It fails to start:

# xe vm-start uuid=f2ba4767-7b4f-b416-3da6-3fe059ebfc37
The server failed to handle your request, due to an internal error.  The
given message may give details useful for debugging the problem.
message: device model failed to initialise: qemu-dm exitted unexpectedly

I've seen exactly the same error when I attach another Linux HVM to an
internal network (i.e. xapi0, xapi1, ...).

Removing the vif, it is possible to boot these HVMs

I notice that the xcp host only has a small number of qemu packages
installed:

# dpkg --list | grep qemu
ii  qemu-keymaps                         1.1.2+dfsg-5             all
       QEMU keyboard maps
ii  qemu-utils                           1.1.2+dfsg-5             i386
       QEMU utilities

while the legacy squeeze/xm environment has packages such as
xen-qemu-dm-4.0, so maybe xcp-xapi is not bringing in all necessary
dependencies?
