Subject: 3.0.5 rc3 paravirt save failures ?
Date: Tue, 1 May 2007 12:55:02 +0100 [thread overview]
Message-ID: <20070501115502.GA27924@redhat.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 1144 bytes --]
I'm seeing a fairly frequent problem when trying to save paravirt domains.
xc_save is failing, and logging the following error:
(XendCheckpoint:349) ERROR Internal error: Frame# in pfn-to-mfn frame list is not in pseudophys
(XendCheckpoint:349) ERROR Internal error: entry 206848: p2m_frame_list[404] is 0x0
(XendCheckpoint:349) ERROR Internal error: Failed to map/save the p2m frame list
Save/restore of fullyvirt on the same box is working pretty well. 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.
Regards,
Dan.
