I tried that syntax but it does not work:
name='Gentoo-32-test'
vif=['bridge=eth0']
bootloader='/usr/bin/pygrub'
disk=[ "tap:tapdisk:aio:/mnt/tb1_store/Xen VMs/Gentoo-32/Gentoo-32.sda1,xvda,w"]
extra='gentoo=nodevfs console=xvc0'
Using config file "./Gentoo-32-test.cfg".
Error: [Errno 2] No such file or directory: 'aio:/mnt/tb1_store/Xen
VMs/Gentoo-32/Gentoo-32.sda1'
I changed the config back to file:/ and tried again, the xm create
process seemed to hang and the block script was stuck:
root 14152 0.0 0.0 17596 1572 ? S< 08:43 0:00
/bin/bash /etc/xen/scripts/block add
eventually it errors Error: Device 51712 (vbd) could not be
connected. /etc/xen/scripts/block failed; error detected.
And the remove script is also stuck:
/bin/bash /etc/xen/scripts/block remove
