Xen domu IO freezes
Clash Royale CLAN TAG #URR8PPP Xen domu IO freezes I installed xen in the Centos 7.4.1708 following the Xen4CentOS guide. And then I installed 3 dom-U guest (2 CentOS7, and 1 Windows server) with full virtualization. After the initial testing when I made system production available, only the linux systems periodically hangs but Windows server system is running alright. The xen kernel is 4.9.63-29.el7.x86_64. The dom-U linux hosts are CentOS 7 (3.10.0-693.5.2.el7.x86_64), and the windows host is Windows Server 2012 R2. The linux kernel for dom-U hosts hangs with the following kernel hang message: > [ 3746.780097] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. > [ 3746.780223] INFO: task jbd2/xvdb6-8:8173 blocked for more than 120 seconds. The tasks in above message are different depending what was running at that moment. The logs end at some point until the new reboot. Sometimes it's still possible to log on to the system, but nothing...
