Xen 4.20 Hypervisor Released With AMD Zen 5 Support, More Performance Optimizations

([Virtualization] 114 Minutes Ago Xen 4.20)


The Xen Project announced the availability today of the Xen 4.20 virtualization hypervisor.

Xen 4.20 brings many notable improvements and performance optimizations. Some of the key takeaways for Xen 4.20 include:

- Security and performance enhancements within the core hypervisor code.

- Xen 4.20 brings support for AMD Zen 5 CPU cores across the Ryzen 9000, Ryzen AI 300, and EPYC 9005 series hardware. This Zen 5 support includes mitigation handling for the SRSO vulnerability.

- Xen 4.20 on Intel CPUs now supports the Paging-Write feature for more efficient monitoring of guest page table updates.

- Removed support for Intel Xeon Phi processors.

- Experimental support for the Armv8-R ISA.

- Xen 4.20 on RISC-V brings enhanced Device Tree mapping and memory management initialization.

- Xen 4.20 enables Undefined Behavior Sanitizer (UBSAN) support across x86/x86_64, ARM64, RISC-V, and PowerPC within the GitLab continuous integration (CI) testing.

In a forest a fox bumps into a little rabbit, and says, "Hi,
Junior, what are you up to?"
"I'm writing a dissertation on how rabbits eat foxes," said the
rabbit.
"Come now, friend rabbit, you know that's impossible! No one
will publish such rubbish!"
"Well, follow me and I'll show you."
They both go into the rabbit's dwelling and after a while the
rabbit emerges with a satisfied expression on his face. Comes along a
wolf. "Hello, little buddy, what are we doing these days?"
"I'm writing the 2'nd chapter of my thesis, on how rabbits devour
wolves."
"Are you crazy? Where's your academic honesty?"
"Come with me and I'll show you."
As before, the rabbit comes out with a satisfied look on his face
and a diploma in his paw. Finally, the camera pans into the rabbit's cave
and, as everybody should have guessed by now, we see a mean-looking, huge
lion, sitting, picking his teeth and belching, next to some furry, bloody
remnants of the wolf and the fox.

The moral: It's not the contents of your thesis that are
important -- it's your PhD advisor that really counts.
