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?
