Yes, this domain has: - Current memory allocation: 8192 MB - Maximum memory allocation: 10240 MB. I have changed the maximum to 8192 MB as a possible workaround; the current memory is rarely up/down scaled anyway. The PVH setting for dom0 has been removed. If you don't here from me anymore,

Hi Juergen, I needed to wait until the VM guest crashed again, so that caused this delay. I have extracted the hypervisor dmesg and the dom0 dmesg which can be found in the PasteBins. It is always the same domain crashing, if that is of any help. Xen hypervisor dmesg:

Hi Juergen, I have noticed that a patch has been developed an awaits the upcoming Linux kernel 4.14, maybe 4.15. In the mean time the server keeps crashing about every 2 days. Do you know a workaround I can apply? Best regards, Arthur Borsboom. On 25 October 2017 at 16:13, Juergen Gross

Since about a month, possibly due to software updates, after a couple of days running several VMs, one of the VM guests crashes and the VM host is not stable anymore. I need to shutdown all the remaining VM guests (if possible) and reboot the server by hardware (sudo reboot hangs). Does anybody
