Merry Christmas and thanks for all that you and your team have done for XCP! Keep up the good work!

Thanks! Just needed to be 200% sure!

As the whole world is shutting down Citrix servers at the moment, just to be sure...

Is XCP-ng safe and not affected by the vulnerabilies in Citrix Application Delivery Controller and Citrix Gateway Server?

Hi,

I read this article on the performance increase HVM has on PV:
https://xen-orchestra.com/blog/debian-pvhvm-vs-pv/

Yeah, I know, we're almost 7 years further

Anyway, as the xcp-ng center and XO these days has a button to simply switch between PV and HVM and back, I was wondering if on my Debian 7.11 and Debian 8.11 PV VMs, switching to HVM is as simple as clicking the button and rebooting.

Well.. it seems to work. The output of Dmsg looks OK. Ethtool shows that the VM is now using HVM
As suggested to check here: https://wiki.xen.org/wiki/Xen_Linux_PV_on_HVM_drivers

So, I suppose my question is simple:
If I switch Debian 7 or 8 to HVM, is there anything else I should do?

Not sure if this is an iOS and iPadOS limitation, but It's not possible to pull up the on screen keyboard to type in the console. I never needed it, till this morning, so never noticed this.

Also, as this did not work, I tried a RDP connection using Microsoft Remote Desktop app, to a windows machine with XCP-ng center. That console only likes the ENTER button (from the RDP app onscreen keyboard). All other keys did not work, so it was impossible to type "fsck -y /dev/xvda" on a VM that needed it's disk checking at boot.

Well done guys!

Before I give these a spin, I assume I need to switch off the automatic windows update xentools update method (which I enabled via XenOrchestra)... right?
