Is CentOS the right distro for KVM host....is it not to "old"?

Post by MrCalvin » 2019/03/15 17:05:19

Just found a PDF from RHEL Storage-Performance-Tuning-for-FAST-Virtual-Machines

One of the adviced given was to make sure you're running the newest kernel and newest version of QEMU.
But isn't RHEL/CentOS one of the distros the use the oldest kernel and software versions?
Can someone enlighten me why CentOS is actually is a good choice?
I understand old = stable, but old is also equal to "missing must-have-features"

Or perhaps RHEL/CentOS's kernel is patched in a way that make it up-to-date, even though it's kernel version is old?

Because about half the authors of most OSS projects work for Redhat?

And don't judge by version numbers: The CentOS/RHEL kernel has substantial portions of its code backported from newer 4.x kernels.

Please see https://access.redhat.com/security/updates/backporting/ for information on backporting of security fixes and features in CentOS and RHEL. Additionally https://access.redhat.com/solutions/2074 may also be of use.
CentOS 6 will die in November 2020 - migrate sooner rather than later!

CentOS 5 is dead, do not use it.
