Hello,

i installed a box with ubuntu 10.04 LTS.

For snapshot functionality i created a logical volume like here: h_t_t_p://weblogs.amtex.nl/index.php/2007/10/08/using_vzdump _snapshot_to_backup_without_downtime?blog=2


Then i tried to install openvz under unbuntu 10.04 LTS, following this howto: h_t_t_p://wiki.openvz.org/Install_kernel_from_RPM_on_Ubuntu_ 10.04

There have been some errors and warnings (please see below), but i got my .deb files an was able to install a kernel.

But now my lvm partitions are not accessable anymore:
"The disk drive for /var/lib/vz is not ready yet or not present"

The lvdisplay command shows my logical volume, but there is an error message "/proc/misc: No entry for device-mapper found. Is device-mapper driver missing from kernel?"


Did i forgot something to enable device-mapper or is it missing in vzkernel?

redhat kernel makes use of lvm2 as a module whereas ubuntu compiles it into the kernel

echo "dm-mod" >> /etc/modules

you will also have some problems with rsyslog as ubuntu 10.04 uses a kernel hack for access to /proc/kmesg

second post will cure any problems with rsyslog and /var/log/messages

if I find time I will update the wiki accordingly.
