Re: [Condor-users] Xen VM universe

You may want to run verify you can connect through virsh 1st.

service libvirtd restart (for RH)
virsh -c xen:///

just to see what happens.

You may also want to check the pre-reqs:

I've changes something (not sure how or what)&  I'm getting a
decernable error now in the vm_ghap about libvir tnot being able to
initialize xen:/// (though I can use virsh to start this domain by

What I did:

I made a copy of condor_vm_xen.sh as condor_vm_xen-debug.sh made a
small edit to make it copy the libvirt config file to /tmp so I could
examine the contents:

       echo "configfile:  $XEN_CONFIG_FILE"
       TMPFILE=`mktemp /tmp/xen-virt.XXXXXXXXX `;sleep 1

I'd done this on an earlier (condor 7.0?) attempt to get teh VM
universe running , this time I got tmp file and I got :

11/20 11:30:42 (fd:7) (pid:20251) ERROR "Failed to create libvirt connection: could not connect to xen:///" at line 1616 in file xen_type.cpp

in the VMGhapLog, surprisingly I still get this after pointing the
config back at the original condor_vm_xen.sh script...

I didn't think to look in the shaddow log before I started getting the
libvirt errors currently I'm seeing:

11/20 04:57:35 (306.0) (18170): Request to run on slot1@xxxxxxxxxxxxxxxxxxxx<>  was ACCEPTED
11/20 04:57:45 (306.0) (18170): ERROR "Error from slot1@xxxxxxxxxxxxxxxxxxxx: Failed to create a new VM" at line 648 in file pseudo_ops.cpp

I guess finding out what I did or didn't do to libvirt is first order
of business, perhaps it's dropping root too soon?
