Ok, after recompiling libvirt 0.7.4 I am able to get it to connect and sort of works with openvz. I always get an error about "error: internal error Could not set UUID". It ends up defining the domain but uses the id of last id+1 instead of 600. If I dumpxml on the domain it created it looks different. Any ideas on this error? Original I passed to virsh: <domain type='openvz' id='600'> <uuid>9626e6b8-584c-729c-9e66-a583577821e6</uuid> <name>600</name> <vcpu>1</vcpu> <memory>4096</memory> <os> <type>exe</type> <init>/sbin/init</init> </os> <devices> <filesystem type='template'> <source name='rhel-5-x86_64-minimal'/> <target dir='/'/> </filesystem> <interface type='bridge'> <mac address='00:50:56:3b:5e:6d' /> <source bridge='virbr0'/> <target dev='veth101.0'/> </interface> </devices> </domain> =========================== dumpxml: <domain type='qemu'> <name>202</name> <uuid>3b20a001-b90a-abbe-a6ef-297f7b265119</uuid> <memory>0</memory> <currentMemory>0</currentMemory> <vcpu>8</vcpu> <os> <type>exe</type> <init>/sbin/init</init> </os> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>destroy</on_reboot> <on_crash>destroy</on_crash> <devices> <filesystem type='template'> <source name='rhel-5-x86_64-minimal'/> <target dir='/'/> </filesystem> </devices> </domain> Thanks, Tom On 3/3/10 3:51 PM, "Thomas Graves" <tgraves(a)yahoo-inc.com&gt; wrote: I just recently started using openvz and I'm trying to use libvirt/virsh with it. I followed the directions on page: http://libvirt.org/drvopenvz.html But I get an error trying to run define with the example config file: virsh define virt.conf error: Failed to define domain from virt.conf error: unknown OS type exe sudo virsh -c openvz:/// list error: could not connect to openvz:/// error: failed to connect to the hypervisor I'm using libvirt 0.7.2 with latest rhel5.4 openvz. Does anyone have more example configuration files or other setup instructions? Does Libvirt allow you to specify other resource limits and controls that openvz has - like vzctl set --devnodes device:rw or vzctl set kmemsize?
