HVM save and restore fails with obscure error message
Last modified: 2007-11-30 17:07:38 EST
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
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.
