You can attach the disk on the usb bus (<target dev='sda' bus='sub'/> - Not 100% sure about this but probably in the right direction) and let the guest automount usb-storage…

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?

Best Regards

Why not ssh?

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!

Best Regards
