[libvirt-users] Error creating a new vm

Hi,

I wonder if anyone can help me with this, I have been trying to get a vm up and
running for a while now and cant for the life of me work out why it isnt
working. The errors I get arnt very helpful and im at a loss as how to debug
this any further.

Here is the command and output that I get...(Also nothing shows up with virsh
list --all after so its starting to install then dropping out)

Hope someone can help. Thanks!

Which libvirt version do you use? If I'm right, it should be
caused by a recent patch.

     /* wait for qemu process to to show up */
     if (ret == 0) {
         if (virFileReadPid(driver->stateDir, vm->def->name,
&vm->pid)) {
             qemuReportError(VIR_ERR_INTERNAL_ERROR,
                             _("Domain %s didn't show up\n"), 
vm->def->name);
             ret = -1;
         }
#if 0
     } else if (ret == -2) {
         /*
          * XXX this is bogus. It isn't safe to set vm->pid = child
          * because the child no longer exists.
          */

         /* The virExec process that launches the daemon failed. Pending on
          * when it failed (we can't determine for sure), there may be
          * extra info in the domain log (if the hook failed for example).
          *
          * Pretend like things succeeded, and let 'WaitForMonitor'
report
          * the log contents for us.
          */
         vm->pid = child;
         ret = 0;
#endif
     }

could you check your guest log, and also libvirtd log?

/var/log/libvirt/qemu/$guest.log
/var/log/messages
