Answering my own post. ;-) It's an irqbalance problem as before, but I used an uncommon solution. ;-) I changed the number of virtual processors from 2 to 1 and everything is fine. In order to avoid further problems with this constellation, I will leave the number of cpus unchanged. Nice easter-days to everyone! Lars. Original Message processed by davidĀ® Urgent Hyper-V problem - please help :-) (29-Mrz-2013 17:52) From: blueo...@larsi.de To:BlueOnyx General Mailing List Hello, I did a yum update on a customers server and after that there is no network connection. I read all the issues with hyper-v and sometime ago Michael noticed a problem with irqbalancing on this server. But this time "service irqbalancing stop" did not change anything. All solutions point me to boot an older kernel, but I can't do this. Everytime I boot the machine, it allways go to the last kernel and changing the grub.conf only results in a broken server, which won't boot anymore. Does anyone has an idea for me? I can boot the server in kernel 2.6.32-279.5.1.el6.i686. Thanks in advance. Lars.
