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 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
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.

That works fine but it is a lot of work to get the new kernels in every time. I''ve never tried windows or freebsd as a domU in the above configuration or any other but I''m sure there are others around here that have.
