Anyone have ideas on what the error message might be trying to tell me.... ? I'm attaching the xend.log & the guest config from xm list --long The host is running 3.0.5 rc3 HV, and 3.0.5 rc4 userspace & arch is x86_64 I don't see anything between rc3 & rc4 HV that is explicitly addressing PV save failures, but doing a new build to check that anyway.
