VMs locking up in PMVE 3.4.6

[m.ardito]

We were thinking of the 4.0 beta idea - as this has a 4.6 kernel

4.2 kernel, of course

Do you have a Haswell CPU like E5-2620v3 or something?

We have the issue with this kind of CPU. Do you suggest something ?

Thanks !

No, sorry - but we have the same problems and also others, i.e. here: http://forum.proxmox.com/threads/20372-Linux-guest-problems-on-new-Haswell-EP-processors

We are up-to-date :


This is recent Supermicro hardware, E5-2630 v3 processors

Here is an example of VM which sometimes crashes (it seems did not happened since a week)

@gslongo - Just a hunch, but have you tried changing the disk type to "no cache"?

It could be total coincidence, however the only crashes we've had this week are on machines with the cache enabled.

It should be fine to disable this cache option, as the RAID controller will still perform its' caching at the hardware level.

Thanks,

Jon

Did you try disabling the disk cache? I have problems with it from time to time and leave all my VMS with no cache

Hi,

Yes we have cache enabled.
We will try without

Thanks

We've currently disabled cache on all VMs.

No crashes so far, but it is early days. Performance does seem better however.

Thanks,

@gslongo - How's things your end?

We've had no issues in 6 days now, which is great .

Still no issues for us, even after returning to stock kernel and build.

We're calling case closed on this.

Thanks for all the help - hope this thread is of use to others at some point!
