Unable to start some VM with Debian 6

Hi,

on Cloudmin GPL running on CentOS 5 + Xen some new VM based on Debian 6 64 bit are unable to start:

Using config file "/xen/smtpsh2.cfg". Using to parse /boot/grub/menu.lst Traceback (most recent call last): File "/usr/bin/pygrub", line 691, in ? chosencfg = run_grub(file, entry, fs) File "/usr/bin/pygrub", line 545, in run_grub g = Grub(file, fs) File "/usr/bin/pygrub", line 203, in init self.read_config(file, fs) File "/usr/bin/pygrub", line 407, in read_config self.cf.parse(buf) File "/usr/lib64/python2.4/site-packages/grub/GrubConf.py", line 287, in parse self.add_image(GrubImage(title, img)) File "/usr/lib64/python2.4/site-packages/grub/GrubConf.py", line 135, in init _GrubImage.init(self, title, lines) File "/usr/lib64/python2.4/site-packages/grub/GrubConf.py", line 86, in init self.reset(lines) File "/usr/lib64/python2.4/site-packages/grub/GrubConf.py", line 104, in reset self._parse(lines) File "/usr/lib64/python2.4/site-packages/grub/GrubConf.py", line 98, in _parse map(self.set_from_line, lines) File "/usr/lib64/python2.4/site-packages/grub/GrubConf.py", line 142, in set_from_line setattr(self, self.commands[com], arg.strip()) File "/usr/lib64/python2.4/site-packages/grub/GrubConf.py", line 107, in set_root self._root = GrubDiskPart(val) File "/usr/lib64/python2.4/site-packages/grub/GrubConf.py", line 56, in init self.disk = str File "/usr/lib64/python2.4/site-packages/grub/GrubConf.py", line 69, in set_disk self._disk = int(val[2:]) ValueError: invalid literal for int(): ev/xvda1 No handlers could be found for logger "xend" Error: Boot loader didn't return any data!

On the same server, another similar installation can run fine with same settings. The only way to start this VM is change the default boot loader to Host System Kernel.

How can this problem be solved? Thanks
