[libvirt-users] [libvirt-user] questions about disk driver virtio and charmonitor

hi all, I have two questions about libvirt. At first, how can I write a XML file that libvirt could give me a command that include this: if=virtio. -drive file=/dev/vg.vmms/lvm-v097218.sqa.cm4,if=none,id=drive-ide0-0-0,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 event I have let the <target dev=vda bus=virtio> the XML file also make the command not include virtio, it's like this: -drive file=/dev/vg.vmms/lvm-v097226.sqa.cm4,if=none,id=drive-virtio-disk0,format=raw,cache=none -device virtio-blk-pci,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0 and my question is, this is command args could enable virtio? or there is some other XML format could let the if=virtio. Second when I boot the vm in the second step after use the kickstart install it. Once in a while, it occurs an error that: monitor socket did not show up.: No such file or > Traceback (most recent call last): File "/home/lingjiao.lc/vmms/backserv/bin/../lib/virtmgr.py<http://lingjiao.lc/vmms/backserv/lib/virtmgr.py>", line 1007, in request_vm dom.create() File "/usr/lib64/python2.6/site-packages/libvirt.py", line 325, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: monitor socket did not show up.: No such file or directory But if I reinstall it, it will be ok. If I install hundreds of VMs once, I think this is a headache. Could anybody help me, how can I disable the charmonitor or solve these problem. Thanks. ________________________________ This email (including any attachments) is confidential and may be legally privileged.
