Re: [libvirt-users] Developing on host machine, running code on guest VM
I am actually having a hard time getting this to work with a CentOS VM..
I built and installed 9p-sac (Stand alone kernel module) and now
[root@thirdspotcloud t2]# cat /proc/filesystems | grep 9p
nodev 9p
[root@thirdspotcloud t2]# lsmod | grep 9p
9p 16414 0
9pnet 39112 1 9p
[root@thirdspotcloud t2]#
but when I run: mount -t 9p -o trans=virtio testmount /opt/workspace/
-oversion=9p2000.L
I get:
mount: wrong fs type, bad option, bad superblock on ecp,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so
I used virt-manager to generate a config:
<filesystem type='mount' accessmode='passthrough'>
<driver type='path' wrpolicy='immediate'/>
<source dir='/var/lib/libvirt/images/testfolder'/>
<target dir='testmount'/>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x08'
function='0x0'/>
</filesystem>
Any ideas?
