And the domU hangs and must be destroyed with "xl destroy nnn"
All Xen frontend and backend drivers are included in the kernel.
I have been searching on the Internet for days without finding any useful suggestion. Anyone here who sees what may cause my problem?
Question
kdvgent
I do not succeed to get my first domU running.
I have lvs containing the file systems for the domU
xen ~ # lvs
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert
backup vg0 -wi-a----- 1.00t
lvcopy vg0 -wi-a----- 1.00t
xnas-portage xgdom -wi-ao---- 10.00g
xnas-root xgdom -wi-ao---- 10.00g
xnas-swap xgdom -wi-ao---- 5.00g
My domU configuration file
xen xen # cat xnas.cfg
kernel = "/xen/kernel/kernel-genkernel-x86_64-3.18.11-gentoo"
ramdisk = "/xen/kernel/initramfs-genkernel-x86_64-3.18.11-gentoo"
memory = 1024
name = "xnas"
vif = [ '' ]
dhcp = "dhcp"
disk = ['phy:/dev/xgdom/xnas-root,xvda1,rw', 'phy:/dev/xgdom/xnas-swap,xvda2,rw', 'phy:/dev/xgdom/xnas-portage,xvda3,rw']
root = "/dev/xvda1 ro"
My domU /etc/fstab
xen xen # cat /mnt/domu1/etc/fstab
# /etc/fstab: static file system information.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
#
# See the manpage fstab(5) for more information.

But when starting my domU with: "xl create -c xnas.cfg"
The file systems are not found:
