We have recently upgraded from xen 3.4.4 to xen 4.1.2 and when completing this upgrade it appears the systems rebooted into the kernel for xen 3.4.4 vs the proper kernel for 4.1.2. We have identified the root cause and rebooted the nodes into the proper kernel that should resolve the issues of instability this has caused. We had upgraded to xen 4.1.2 in the first place to correct issues with IPv6 in Xen 3.4.4
最近我们升级xen 3.4.4到 xen 4.1.2,升级完成后系统重启,但进入了错误的xen 3.4.4内核而非正确的4..1.2内核。我们发现是根权限原因并重启节点为正确内核,解决了由此导致的不稳定性。升级也修正了IPv6下该问题。
