Hi everyone,
I'm currently trying to get Condor to run virtual machines using the KVM
hypervisor, but I'm having some problems.
I have a few machines set up to run VMs through Condor, and, based on
their log files, they are attempting to start vm universe jobs when I
submit them. The virtual machine image, however, never gets loaded, and
the job fails. Condor tries to resubmit it, but it just keeps failing. I
think this is due to permissions issues related to bridged networking.
It appears that bridged networking is broken in KVM for non-root users.
When you try to start a virtual machine, KVM (through qemu) tries to
create a TAP device to connect through your network bridge. Creating a
TAP device, however, appears to be restricted to root users, and it
throws an error when you try to start a VM using a non-root account.
So, my question is - can Condor run virtual machines that use bridged
networking through KVM? Is there a workaround to get past the TAP device
issue? Does anyone have any experience with Condor and KVM?
Any insight would be very much appreciated.
Thanks,
Ryan
