Hello, first time poster. I’ve created a one-node cluster on an intel NUC 10 (NUC10FNH) using latest phoenix image. install went fine after a couple of hardware bumps but node is up, CVM is running etc. The issue I’m having is I can’t power on any VMs I create. It only gives a generic “InternalException” error. In the uhura.out log, there are these entries “Error: HypervisorError: internal error: QEMU unexpectedly closed the monitor” and “qemu-kvm: Address space limit 0x7fffffffff < 0x4bcbfffffff phys-bits too low (39): 61”. Having a hard time trying to make sense of this. I’ve read other people running on the same hardware with no issues, maybe it’s the specific version of the CPU (it’s an i7-10710U). one-node cluster, 64GB RAM, one 500GB m.2 SSD and one 500GB SATA SSD. booting off a 64GB usb drive. Any info would be appreciated. Thank you.

Hi Oscar,

Hope you’re well.

Is this an install of CE directly or was it upgraded after installation? (I’ve seen this with AHV 10 but not earlier)

A clue is the 39 bits being quoted in the error message that would tie up with your CPU theory on a consumer grade CPU.

A few things to check, does the VM boot if you set a low amount of memory e.g. <1GB?

Can you confirm IOMMU is enabled within the BIOS?

Outputs of the below would help too from the AHV host:

uname -a

ls /sys/class/iommu

grep ‘address sizes’ /proc/cpuinfo

 

Thanks,

Kim

Thanks for your response.

Yes, after I did the initial install first thing I did was run the LCM and upgraded everything.

I have verified that VT-d was enabled in the BIOS settings and have upgraded to latest BIOS/firmware.

I set the VM to as low as as 256MB and same response when powering on.

Here are the results of those commands:

# uname -a
Linux NTNX-xxxxxxxx-A 6.1.92-10.0.1s2c14r5.el8.x86_64 #1 SMP Wed Dec 11 12:00:00

# ls /sys/class/iommu
dmar0  dmar1

# grep 'address sizes' /proc/cpuinfo
address sizes    : 39 bits physical, 48 bits virtual
address sizes    : 39 bits physical, 48 bits virtual
address sizes    : 39 bits physical, 48 bits virtual
address sizes    : 39 bits physical, 48 bits virtual
address sizes    : 39 bits physical, 48 bits virtual
address sizes    : 39 bits physical, 48 bits virtual
address sizes    : 39 bits physical, 48 bits virtual
address sizes    : 39 bits physical, 48 bits virtual
address sizes    : 39 bits physical, 48 bits virtual

 

I’m just surprised that everything else installed normally including the CVM which is a VM but not any other one. One other weird thing is that the CVM does not show up in the list of VMs even when checking the box to show the controller VMs.

Thanks.
