<p class="MsoNormal" style="text-indent:28.0pt"><span lang="EN-US" style="font-size:14.0pt">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:</span><span lang="NL-BE"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:12.0pt">mount /dev/vda1 /mnt</span><span lang="NL-BE"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:14.0pt"> Does Libvirt has some API which can send the guest operation(like mount/umount) from host to guest?</span><span lang="NL-BE"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:14.0pt">Thus I can do the operation on host and need not to log on guest to do the operation.</span><span lang="NL-BE"><o:p></o:p></span></p>
