[libvirt-users] 答复: How could I do the guest mount operation from the host?

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.

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: 李笳平 [mailto:lijiaping@yovole.com]<mailto:[mailto:lijiaping@yovole.com]> Verzonden: vrijdag 6 november 2015 10:14 Aan: Dominique Ramaekers; &#39;libvirt-users(a)redhat.com&#39; Onderwerp: 答复: [libvirt-users] How could I do the guest mount operation from the host? 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?

Verzonden: vrijdag 6 november 2015 3:34 Aan: libvirt-users@redhat.com<mailto:libvirt-users@redhat.com> 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!
