Description Stephen Tweedie 2006-11-29 14:45:24 UTC
fv save/restore is not supported, but xen tries to do it anyway and fails with
an obscure error message.  The tools really need to fail cleanly in this case.

 +++ This bug was initially created as a clone of Bug #217610 +++

Description of problem:

I am unable to save a running guest on a full virt system. My test case has a
guest installed with rhel3u8. Turned SELinux off to eliminate issues and xm save
still fails.

Test system is and AMD tyan i686 - Cpus:4 Memory:1803 MB 

# xm list
Name                                      ID Mem(MiB) VCPUs State   Time(s)
Domain-0                                   0     1803     4 r-----  26086.1
rhel3u8-i386                             164      600     1 -b----     21.0

# xm save rhel3u8-i386 /var/lib/xen/images/save.img
Error: /usr/lib/xen/bin/xc_save 21 164 0 0 0 failed
Usage: xm save <Domain> <CheckpointFile>

Save a domain state to restore later.
# getenforce

Linux amd-tyan-03.lab.boston.redhat.com 2.6.18-1.2747.el5xen #1 SMP Thu Nov 9
19:33:10 EST 2006 i686 athlon i386 GNU/Linux
# rpm -q xen xen-libs

How reproducible:

Steps to Reproduce:
1. install rhel3u8 full virt guest
2. xm create guest

Comment 2 Daniel Berrange 2007-06-14 19:04:03 UTC
HVM save & restore is already implemented as a result of bug 214995, so this bug
is no longer relevant.
