刚将我们的XenServertesting机从5.6升级到6.0，其中一个虚拟机（ubuntu-server 10.04 LTS）将不再启动。 XenCenter出错;
9/11/2011 3:48:23 PM Error: Starting VM 'TestDom-Ubuntu' - Traceback (most recent call last):
File "/usr/bin/pygrub", line 873, in ? - data = fs.open_file(chosencfg["kernel"]).read() - IOError: [Errno 2] No such file or directory
任何人都遇到过这个问题？
编辑; 我已经更新了在xen引导相关的参数，仍然收到问题;
