[libvirt-users] how to use command 'guest-file-open' for Windows server 2012R2 vm

[刘梦可]

hello,


I am using  libvirt 1.2.17 on CentOS 7.2 - kernel
3.10.0-327.13.1.el7.x86_64. The command guest-file-open failed to open
with error "this feature or command is not currently supported", the
detail is as below:

virsh qemu-agent-command instance-00000015
"{\"execute\":\"guest-file-open\",
\"arguments\":{\"path\":\"\tmp.txt\",\"mode\":\"r\"}}"
error: internal error: unable to execute QEMU agent command
'guest-file-open': this feature or command is not currently supported.

The guest instance-00000015 is a Windows server 2012R2, and I
installed the qemu-guest-agent by the file qemu-ga-x64.msi from
virtio-win-0.1.126. It can be running in guest.

Doesn't the qemu-guest-agent in Windows VM support guest-file-*
commands? How or when can I use the command guest-file-* command?

Thanks very much!!
