dears. I can not solved the problem: vzctl works. But how do I connect to Virtuozzo? Using the openvz
driver it doesn't work out of the box: virsh # connect openvz:///system error: Failed to connect to the hypervisor error: no connection driver available for openvz:///system

This may be a simple case of your libvirt binary not being pre-compiled with openvz support. What distro are you using? What does: virsh --version=long display? It may be that you have to recompile libvirt from a tarball and explicitly request that the openvz code be compiled, if the pre-built binary from your distro omits that driver. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org

Maybe the problem is that OpenVZ and Virtuozzo are not identical. See this thread on the user list about the difference between ctid and vpsid: https://www.redhat.com/archives/libvirt-users/2011-May/msg00070.html https://www.redhat.com/archives/libvirt-users/2011-July/msg00031.html I looked this up in the OpenVZ source history at that time and vpsid was changed to ctid at some time. So the OpenVZ driver needs to deal with this difference as it seems that Virtuozzo is based on newer OpenVZ that uses ctid. -- Matthias Bolte http://photron.blogspot.com
First ,thanks for you help but I am very sorry,I do not konw how to recompile libvirt to support openvz. My os is centos6,its own libvirt version is 0.8.1 please tell me how to recomplie libvirt.because I do not find libvirt makefile. 在 2011-10-11 16:50:19，"Matthias Bolte" <matthias.bolte@googlemail.com> 写道：

Accidently sent this directly to OP, You'll want to download the libvirt SRPM for CentOS 6. Based on the comment from the spec file , RHEL and CentOS is purposely not compiled with openvz, # RHEL doesn't ship OpenVZ, VBox, UML, OpenNebula, PowerHypervisor, # VMWare, or libxenserver (xenapi) %if 0%{?rhel} %define with_openvz 0 To enable openvz you change that define to 1 and then rebuild using the spec. You can extract the SRPM contents with... rpm2cpio libvirt-xxxx.src.rpm | cpio -dimv Then follow this documentation, http://wiki.centos.org/HowTos/RebuildSRPM , to rebuild a new RPM. Hope that helps, - Trey
