Re: [Xen-users] DomU crashes sometimes
32-bit paravirt clients on 64-bit domU don't work well with centos,
either do 64 on 64, or use HVM, or 32 on 32. At least that was
my experience when I tried it.

I've got Xen 3.1.0-53.1.14.el5 installed on CentOS 5.1 x86_64 (kernel
2.6.18-53.1.14.el5xen). Hardware is Opteron 1212 on a SuperMicro
MNL-H8SSL-i2 motherboard (ServerWorks HT1000 chipset).
When I try to startup a new CentOS DomU (using the vmlinuz and initrd as
specified in this guide
http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU) the initial
install crashes at least 50% of the time. The error lines in my xend.log
are:
[2008-03-25 08:05:55 xend.XendDomainInfo 7375] WARNING
(XendDomainInfo:923) Domain has crashed: name=resolver3 id=9.
[2008-03-25 08:05:55 xend.XendDomainInfo 7375] DEBUG
(XendDomainInfo:1557) XendDomainInfo.destroy: domid=9
[2008-03-25 08:05:55 xend.XendDomainInfo 7375] DEBUG
(XendDomainInfo:1566) XendDomainInfo.destroyDomain(9)
The console doesn't report any errors, it just drops me back to the
Dom0, last thing displayed is whatever package it happened to be trying
to install at the time.
How can I track down this problem to a configuration or hardware
problem? My thoughts right now are either I'm not using the right initrd
and vmlinuz (I was using the 32-bit initrd and vmlinuz for the DomU
install from http://mirror.centos.org/centos/5/os/i386/images/xen/), or
some part of my hardware is tripping out.
Any thoughts?
Thanks!
Donald
