Hello,
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[212]: 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?
Regards,

Yes, and it's listed in the Release Notes (https://wiki.centos.org/Manuals/ReleaseNotes/CentOS7#head-281c090cc4fbc6bb5c...) ....
So you can't run in PV mode with the 7.4.1708 kernel, but you can use the centosplus kernel, which has the added patch/config.
