[Xen-users] after centos 5 yum update xen guest won't boot

["Peter Peltonen" <peter.peltonen@xxxxxxxxx>]

After a yum update my two guests that had been shutdown do not start
any more. I have two other guests running that seem to work okay but I
am now afraid that they won't come up again if I restart them.

I am running CentOS5 with kernel 2.6.18-8.1.8.el5xen. Previously I had
following xen versions installed:

Oct 14 23:45:10 Updated: xen-libs.i386 3.0.3-25.0.4.el5
Oct 14 23:46:05 Updated: xen.i386 3.0.3-25.0.4.el5

After a yum update I now have:

Jan 03 22:22:59 Installed: kernel-xen.i686 2.6.18-53.1.4.el5
Jan 03 22:23:55 Updated: xen.i386 3.0.3-41.el5

I have now two guests that won't boot. This is what I get after
issuing `xm create web04`:

Using config file "/etc/xen/web04".
Error: destroyDevice() takes exactly 3 arguments (2 given)

My config file looks likes this:

name = "web04"
memory = "512"
disk = [ 'phy:/dev/VolGroup00/LogVol03-web04,xvda,w', ]
vif = [ 'mac=e9:00:36:fe:dc:e0, bridge=xenbr0', ]
vfb = ["type=vnc,vncunused=1"]
#uuid = "cc64dbee-64f6-4f6b-9d3f-fc3e185206bc"
bootloader="/usr/bin/pygrub"
cpus = "^0,1" # run only on cpu 1
vcpus=1
on_reboot   = 'restart'
on_crash    = 'restart'

This is what comes to /var/log/xen/xend.log:

Is anytone else with CentOS 5 experiencing this kind of problems?
Should I try downgrading?
