This will therefore be a kernel issue not a hypervisor one. It sounds like a backend one given the issue is with both new and existing Wheezy guests. > We tested the current lenny kernel linux-image-3.16.0-4-amd64 as well > as the backport linux-image-4.1.0-0.bpo.1-amd64 on the dom0 as well > as the domU. (I suppose you meant s/lenny/jessie/ ;-) These are kernel ABI versions, the package release versions are things like 3.16.7-ckt17-1 or 4.2.5-1~bpo8+1, which yu can either get from dpkg or from /proc/version (at the end, before the date, I think). If you can let me know the versions then I can more sensibly reassign this to the kernel packages. It will also give some baselines to see what if any fixes we do or don't have. > The problem happens with newly created domUs via 'xen-create-image', > as well as with older domUs which have been migrated from a debian > wheezy dom0.
