[libvirt] nested VMs

I tried nesting VM's but the hw virt flags are not passed to the next level QEMU-CPU. What version is this going to be available so we have reasonable acceleration? -Gerry

There was a recent patch and response about this: https://www.redhat.com/archives/libvir-list/2009-November/msg00304.html Hope that helps, Paul -- Paul Jenner <psj@familyjenner.co.uk>

Thanks Paul. So I guess this would be in 0.7.3 then. -Gerry

No, because the patch wasn't applied, see the reply Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel@veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

Ok, I had read it but I didn't read the followup. So there was an alternate proposal on how to accomplish setting the svn/vmx flags for nested cpus. Did this method then get into 0.7.3 ? -Gerry
