Proxmox on ESXI 6.7, machinces are freezing with high I\O or CPU

[eviatar834]

Hi Everyone,

We are using Proxmox 7.8 on ESXi 6.7 behind, we are getting every few minutes absolute freeze until we hard reboot for it(Sometimes we are seeing 100% of CPU on one machine), when checking the ESXI behind the scenes the CPU and Disks are working regular without any substantial spikes.

(We migrated from GCP solution to ESXi Solution and it started).


I was wondering if any of you experienced such.

Thanks!

How many core for each Proxmox? What reservation did you give each core in vmware? If still at 0, bump that up to at least 500 if not 1000 times the number of cores.

I assume this is just for POC or some sort of testing? Layering hypervisors takes a performance hit, and generally you are going to want one or the other, not both.
