libvirt users - Nov 2015 - Re: How could I do the guest mount operation from the host?

Hi all,
       When I attach a disk like this:
<disk type='file' device='disk'>
        <driver name='qemu' type='qcow2'
cache='none'/>
        <source file='/kvmdata/disk/dk389_581.img'/>
        <backingStore/>
        <target dev='vda' bus='virtio'/>
        <alias name='virtio-disk0'/>
        <address type='pci' domain='0x0000'
bus='0x00' slot='0x07' function='0x0'/>
</disk>
And then I use “fdisk -l” on the guest, can find the disk info, if I want to
mount a disk, I should log on the guest and use the command just like:
mount /dev/vda1 /mnt
       Does Libvirt has some API which can send the guest operation(like
mount/umount) from host to guest?
Thus I can do the operation on host and need not to log on guest to do the
operation.
       Thanks!

Why not ssh?

Hi,
       Thanks for your response!
But when I use the ssh, I need to know the guest password, and actually it
belongs to network communication. I don’t know if the libvirt has some means
just
like to control the domain to implement the operation?
