Hi
After a bit of googling on populate on demand I realized.
strange that it worked under 7.4.1.

if I understood correctly, it is the dynamic ram assign with min / max.

after I entered a fixed size for ram, the start worked fine.

thank you for the great work

@christianuhlmann said in XCP-ng 7.5.0 Release Candidate:

my first host with xcp-ng upgraded successful to 7.5 (Intel NUC) without an error.
thanks for the great job !

second server has also been updated successfully.

the third server I use pci passthroug for 2 DVB cards.
So far that was excellent under 7.4.1.

Since upgrading to 7.5 I get the following error if i want to start the vm with the passthroug pci devices:

vm.start

all seem ok

Does anyone have any idea what that might be?
does anyone have an upgrade to 7.5 with pci passthroug on the run?

Thanks and Greetings

Hi @stormi

can you post some short update?
I do not want to jostle, but I'm curious about 7.5.
