When optimizing a Linux private image, you need to change the disk identifier to UUID in both the fstab and GRUB configuration files, and install native Xen and KVM drivers. To ensure that you can successfully install native Xen and KVM drivers, you must uninstall the PV driver from the ECS.
ps -ef | grep uvp-monitor
The PV driver is installed in the OS if the following information is displayed:
root 4561 1 0 Jun29 ? 00:00:00 /usr/bin/uvp-monitor root 4567 4561 0 Jun29 ? 00:00:00 /usr/bin/uvp-monitor root 6185 6085 0 03:04 pts/2 00:00:00 grep uvp-monitor
For how to open the CLI, see the OS manual.
The PV driver is uninstalled successfully. Reboot the system for the uninstallation to take effect.
-bash: /etc/.uvp-monitor/uninstall: No such file or directory
# rpm -qa | grep uvp
Information similar to the following is displayed:
libxenstore_uvp3_0-3.00-36.1.x86_64 uvp-monitor-18.104.22.1685-3.1.x86_64 kmod-uvpmod-22.214.171.1245-3.1.x86_64
rpm -e kmod-uvpmod
rpm -e uvp-monitor
rpm -e libxenstore_uvp
