Hi,
I recently tried to hot plug some memory on a VM running CentOS 6.9 with ovirt-guest-tools installed.
oVirt version is 4.2.1.6-1.el7.centos
I was careful to increment a multiple of 256 MB as specified in https://www.ovirt.org/develop/release-management/features/virt/hot-plug-memo... (4 GB -> 6 GB , maximum memory configured for the VM was 8 GB)
However the VM was marked as with a pending change for next reboot. Am I missing some non-default configuration requiered for memory hot-plug to work?
No, you're not. Now the vm is seeing the base memory (4GB) you were seeing at boot, plus additional memory (2GB added). Next time you'll boot the vm, the system will see a single block of 6 GB. That's the difference.
