Subject: support for more than 32 VCPUs when migrating PVHVM guest
Date: Mon, 02 Feb 2015 11:47:56 +0100	[thread overview]
Message-ID: <87k300wpwj.fsf@vitty.brq.redhat.com> (raw)

Hi Konrad,

I just hit an issue with PVHVM guests after save/restore (or migration),
if a PVHVM guest has > 32 VCPUs it hangs. Turns out, you saw it almost a
year ago and even wrote patches to call VCPUOP_register_vcpu_info after
resume. Unfortunately these patches never made it to xen/kernel. Do you
have a plan to pick this up? What were the arguments against your
suggestion?

Thanks,

--
