What is Viridian?

Forza

Hi,

I just noticed a new toggle called "Viridian". What exactly does this do and what impact does it have if it is on or off?

https://github.com/vatesfr/xen-orchestra/issues/6572

There is a hotfix from Citrix that seems to indicate that viridian should be enabled for optimal performance. https://support.citrix.com/article/CTX258320/hotfix-xs80e003-for-citrix-hypervisor-80
I did check and it seems some vms have it enabled and others not.

Hi,

You should really read our release blog post for Xen Orchestra, this is where you can learn everything for each release: https://xen-orchestra.com/blog/xen-orchestra-5-79/#toggle-for-viridian-extensions

Thanks. Then, what about Linux guests? Most of mine seem to have this enabled, but not all. I do know that the Linux kernel supports Hyper-V extensions, so is it an advantage on Linux too?

No, it's useless on Linux.
