Hello,
I''m running Ubuntu 8.04 server that I''ve been testing out
using LVM based
xen virtual servers. The install went as it should, then I made my first
test image using:
xen-create-image --hostname=test1.test.com --lvm=vg0 --size=10Gb --swap=1Gb
--ip=192.168.31.231 --force --memory=50Mb --arch=amd64 --debootstrap
After it finishes I use xm create to start the virtual machine but I keep
getting:
Error: (38, ''Function not implemented'')
I even tried uninstalling, then reinstalling xen but that didn''t help.
Has
anyone seen this before, or know how to take care of it?
Here''s the configuration file I''m using:
# Configuration file for the Xen instance test1.tlthost.net, created
# by xen-tools 3.8 on Sun Mar 28 14:46:54 2010.
# Kernel + memory size
#

ramdisk = ''/boot/initrd.img-2.6.24-27-xen''
memory = ''50''
#
# Disk device(s).
#
root = ''/dev/xvda2 ro''
disk = [
''phy:/dev/vg0/test1.tlthost.net-swap,xvda1,w'',
''phy:/dev/vg0/test1.tlthost.net-disk,xvda2,w'',
]
#

Try building from source downloaded from http://www.xen.org/products/xen_source.html If you don''t know how to build from source, then the easiest way to gen xen working is to use a Linux distro which has good xen version bundled and supported, and widely used. Centos or opensuse (with latest updates) should be a good choice. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

RE: [Xen-users] Re-occuring error trying to set up first DOM
Hi Thanks for the response. When I first installed it, I turned on the backports. What I''ve tried now is shutting them back off, completely uninstalling the whole thing, then reinstalled it. After a reboot, and running the same xen-create-image, I checked lvdisplay and it showed the two new LV''s. Then, when I ran xm create /etc/xen/test1.test.com.cfg I get: Error: Device 0 (vif) could not be connected. Hotplug scripts not working. After a web search I found this solution in the comments at http://www.debian-administration.org/articles/396: Now if you try to boot a domU it will fail with: Error: Device 0 (vif) could not be connected. Hotplug scripts not working. You need to link the xen-backend.rules file in /etc/udev from /etc/udev/rules.d - cd /etc/udev/rules.d ; ln -s ../xen-backend.rules xen-backend.rules This will make the vif error go away, now you''ll be getting cannot mount fs errors, unknown block device. This is because the initrd is now required for your domU to boot, so add this to your domU config file(s): ramdisk = "/boot/initrd.img-2.6.16-2-xen-686" After reading that, I uninstalled/reinstalled to start fresh. This time I made the fixes as I went. Now it''s working perfectly. Tom -----Original Message----- From: Fajar A.
