$ ./virsh create os.xml error：create domain from os.xml failure error：(domain_definition):14: Premature end of data in tag domain line 1 (null) ^
That says your <domain> tag is incomplete. Sure enough...
$ cat os.xml <domain type='qemu'>
You opened it...
<name>testvm</name> <memory>1048576</memory> <os> <type arch='x86_64'>hvm</type> </os> <devices> <disk type='network'> <source protocol="sheepdog" name="testvdi"/> <target dev='hda' bus='ide'/> </disk> <graphics type='vnc' port='-1' autoport='yes'/> </devices>
...but never closed it with </domain>.
Could anyone give me some help? Thanks.
Rather than writing XML by hand from scratch, I highly recommend using a higher level program like virt-manager to create a scratch VM, and then use 'virsh edit' to hand tune the resulting XML. That way, you are less likely to forget something essential, and will at least have the benefit of seeing how libvirt indents constructs rather than struggling to visually pick out the indentation with everything starting on the first column. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

A stupid mistake. Thanks for your reminder ;-) [...]
