Yes, my modification is like you. I doubt that if the mount operation on the host is reasonable… And what is p9? Best Regards From Jiaping LI 发件人:

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… Van:

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 From Jiaping LI 发件人:

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… Van:

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 From Jiaping LI 发件人:

Namens ??? 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!
