[xen-tools-discuss] Problem: Ubuntu 14.04 LTS DomU via xen-create-image on Debian Wheezy Dom0

Wed Apr 23 17:44:34 CEST 2014

Hi,

i tried to install the new ubuntu via xen-tools on my debian wheezy
xen-setup.

I added the new symlink in the debootstrap folder
(/usr/share/debootstrap/scripts/) as following, cause I saw in the actual
package of xen-tools in ubuntu 14.04 that the link is still to gusty.

lrwxrwxrwx 1 root root    5 Apr 23 16:10 trusty -> gutsy

Then I added the sym-link in the folder (/usr/lib/xen-tools) as following
cause the last version of ubunto was also pointed to karmic:

lrwxrwxrwx 1 root root    8 Apr 23 16:34 trusty.d -> karmic.d

Then I tried to install as followed:

xen-create-image --hostname=test --ip=xxx.xxx.xxx.xxx
--gateway=xxx.xxx.xxx.xxx --netmask=255.255.255.0 --pygrub --size=20G
--dist=trusty --bridge=xenbr0 --install-method=debootstrap
--mirror=http://de.archive.ubuntu.com/ubuntu/ --role=udev

The Setup starts as expected but after the following line in the log-file of
/var/log/xen-tools/test.log xen-tools stopped working

I: Base system installed successfully.

A few minutes later after any response the process terminates without any
error or warning. But the lvm of the new device is still mounted in tmp and
it seems that udevd is still accessing some files inside:

so I cannot umount the tmp-device and I don´t know if I can kill this udevd
process without having issues on the root-server.

I tried to search for processes who still working on the image creation. I
searched via ps aux for perl, xen-create-image, debootstrap, the tmp folder
and so on.

My Questions are: 

-          What is this udevd deamon does with the files ? can I kill it or
doing something else to umount the tmp-device again

-          Are there any ideas or issues of using 14.04 lts on xen-tools

Any help would be very great.

Thank you very much!

Greetings

Dominik
