I wouldn't know how to check for certain. I don't know much about Centos6 yet, just that it's supposed to be a clone of RedHat6 minus the commercial support. I did find this from a Citrix forum Re: Death of multi-os Virtualization? http://forums.citrix.com/message.jspa?messageID=1456321 The latest Linux kernels, including the RHEL6 kernel, leverage a capability called paravirt_ops -- which means that the kernel is enabled right out of the box to work properly in a paravirtualized Xen environment (as well as other paravirtualization) -- without needing a special "xenified" kernel. One of our SEs has taken it and, with a small number of simple manual steps, gotten it up and running without a special kernel. Red Hat's no longer shipping a Xen hypervisor doesn't affect this at all. So it looks like the CentOS kernel should be a paravirt_ops (same as pv-ops I think) kernel. Shouldn't what I'm doing work with that kernel? > Have you considered installing as an hvm guest? I'm having a hard time finding Opensuse virtualization "DocsForDummies". I'd consider anything that works right now. If you can help me tweak my config I'll try that. I'd read in some older threads that you lose performance using a fully- versus para-virtualized Guest. Is that still an issue these days? Greg -- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
