Yes, my modification is like you. I doubt that if the mount operation on the host is
reasonable…
And what is p9?

For usb I meant something like:
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2' cache='none'/>
<source file='/kvmdata/disk/dk389_581.img'/>
<target dev='sda' bus='usb'/>
</disk>
If you want to use fiesystem passtrough, I think you have to look at p9 filesystem. I’ve
used it before and it worked like a charm. This does require some setup in the guest…

Hi,
I have tried usb and it doesn’t work. I don’t know if the filesystem tag could
work…
I find in the formatdomain docs about the filesystem:
<filesystem type='mount' accessmode='passthrough'>
<driver type='path' wrpolicy='immediate'/>
<source dir='/export/to/guest'/>
<target dir='/import/from/host'/>
<readonly/>
</filesystem>
The description of filesystem is: A directory on the host that can be accessed directly
from the guest.
I don’t know what the format should be and make the the disk image
/kvmdata/disk/dk389_581.img in the host
mount to the guest /mnt directory.
Best Regards

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?

Onderwerp: [libvirt-users] 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!
Best Regards
