Solved - Problem running virtual machines on HPE ProLiant DL385 Gen11

[Clint Dilks]

Hi,

I have a server running Ubuntu 22.04 and VirtualBox 7, all tools appear to be working but virtual machines will not run.

Using the graphical tools and X-forwarding I can create a virtual machine and get to the point where it should start. Upon starting the virtual machine a console window appears but a BIOS never appears.

vboxmanage showvminfo states the virtual machine is Running.

If I export a virtual machine created on this server to another system via an OVA file. The imported VM starts as expected.

As the primary error seems to be about not getting screen captures here is some additional info about the server.

Thanks in advance for any troubleshooting suggestions that you have.

Hi!

Do Linux VMs work if you disable Nested Paging for them in the settings?
(this also requires disabling Nested Virtualization/AMD-V and will cause issues with Windows VMs)

Edit: I just discovered that the Linux kernel boot parameter "no5lvl" works around this issue!
(5-level paging has been introduced to AMD in Zen 4, our new AMD EPYC 9334 with Supermicro mainboard suffered from the same issue)

Thank you! This seems to be the issue.

I am testing now
