I stumbled upon a strange problem with CentOS upgrade on XenServer environment, and I would like to ask if someone has this issue as well:
XenServer 7.1, the VM is CentOS7, with kernel
3.10.0-514.26.2.el7.x86_64 running in PV mode When I upgrade the kernel (running with yum update kernel), after reboot in the VM console it says “dracut-pre-udev: modprobe:
ERROR: could not insert ‘dm-mod’: Cannot allocate memory” and after a while it drops to dracut shell
If I boot from from an old kernel with the updated kexec-tools/dracut, it’s fine.
Anyone experiencing this issue?
