Evening All,
Would be grateful if anyone can offer guidance on how to fault find this issue. Or solve it :). The google Fu I have used thus far hasn't really help.
All appear to be working great. However over a period of about 3 - 4 weeks the VM's slow down. For example the Windows 10 VM will become noticeably slower.
Rebooting the physical server instantly brings the VM's back to their zippy self.
This is a pretty much an out of the box installation
I haven't found anything obviously wrong.
The only thing I have seen is that some of the CPU's are getting very busy when the issue presents. Whereas when "all" appears OK all CPU's are pretty much around 12% usage.
I have just applied the following pool patch's
- Linux firmware 20190314
- microcode_cti 2.1
- xen-dom0-libs 4.13.4
- xen-dom0-tools 4.13.4
- xen-hypervisor 4.13.4
- xen-libs 4.13.4
- xen-tools 4.13.4
