virsh: Cannot start FC7 domains in FC8
Last modified: 2009-01-09 00:24:34 EST
I have several (5) domains defined in fc7. None of them can be started after
upgrading to FC8. The FC8 installation is a fresh install, not an update.
Version-Release number of selected component (if applicable):
How reproducible: Always.
Steps to Reproduce:
[root@hemulen xen]# virsh define fedora32.xm.xml
Domain fedora32 defined from fedora32.xm.xml
[root@hemulen xen]# virsh start fedora32
libvir: Xen Daemon error : POST operation failed: (xend.err 'int argument required')
error: Failed to start domain fedora32
Domain started as in FC7
The problem seem to be twofold:
In the file /usr/lib64/python2.5/site-packages/xen/xend/image.py, line 251:
info = xc.xeninfo()
if 'hvm' not in info['xen_caps']:
This test seems to fail, but should not:
[root@hemulen xen]# /usr/sbin/xm info | grep hvm
xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32
Further on, in line 420 (same file)
ret.append("%s:%d%s" % (vnclisten, vncdisplay, vncopts))
seems to trigger the exception. Untested error condition?!

Failing domain definition
This definition worked OK in FC7. I have 4 other domains, all working in FC7
and giving the same error in FC8
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
