QEMU Guest Agent cannot be installed on AlmaLinux 10 from ISO

The article contains the following terms:

Problem

It is not possible to install QEMU Guest Agent on AlmaLinux 10 deployed from an ISO image using the platform's tools. Only VM power on, power off, reboot, and delete operations are available.

The problem occurs on nodes running on AlmaLinux 8 due to an outdated kernel version. AlmaLinux 10 uses the XFS file system with options bigtime=1 and inobtcount=1, which are enabled by default in kernel 5.15 and newer. AlmaLinux 8 runs on kernel 4.18, which does not support these features.

Solution

You can solve the problem in one of the following ways:

update the cluster node OS from AlmaLinux 8 to AlmaLinux 9. For more information, see the article Server requirements for the cluster;

update the AlmaLinux 8 kernel to version 5.10 or newer via ELRepo:

Import ELRepo GPG keys:

rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
rpm --import https://www.elrepo.org/RPM-GPG-KEY-v2-elrepo.org

2. Install ELRepo:

dnf install https://www.elrepo.org/elrepo-release-8.el8.elrepo.noarch.rpm

3. Install the new kernel version:

dnf --enablerepo=elrepo-kernel install kernel-ml

4. Reboot the server:

reboot

5. Check the kernel version:

uname -r
