I did an upgrade test and discussion with Vladi, the original issue was due to not waiting enough after an upgrade for the management server to copy all the systemvm.iso/files/scripts to the XS host post-upgrade. In the latest upgrade env created by Vladi, from 4.14->4.15 with XS71, we couldn't reproduce the issue. However we had to restart the systemvms a few times due to a certificate setup issue likely caused due to: - CPU pressure - XS hosts are run inside VM, some cpu entropy is required to create keystore and certificates - this applies to only to SSVM and CPVM - Once SSVM and CPVM were up and connected, we were able to deploy a new VM on a new network that came up OK - We found that VRs failed on XS hosts with already too many VMs - VRs appeared to run slow on these hosts and had errors in running the get_template_version domr script, this didnot happen on XS hosts with less num. of VMs From experience I've seen VMs runs slow on XS65, 71; they appear to run faster on more recent XS version (it could also be a hvm setting). @vladimirpetrov can you add your notes/findings and confirmation. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
