Hi Peter I experienced a similar problem. I believe it is due to interface renaming that happens at boot. Unfortunately I don't have access to my machines so I can't check the specific thing you need to do but do a search for "XenServer interface rename" and hopefully you'll get enough pointers. If I remember correctly I had to edit a file that is used by the rename process to set it to my original nic. Eg eth1 had been turned into eth13. This happened with 5 of my 8 nics. After putting them all back, I rebooted and was back in business.
Hope this helps Carlos > On Dec 5, 2013, at 3:15 PM, Peter Zhai <peter.z...@gmail.com> wrote: > > Hello, > > My cloudstack 4.02 environment has 10 Xen 6.0 hosts ,i did not change > anything lately but start from last week ,many of my Xen hosts will lost > NIC after reboot ,which caused the VM instance on those hosts are not able > to start also. > > I guess it is not pool master issue because some of the slave host still > function .
