Subject [Solved] Compatibility of CS 4.5.1 with XenServer 6.5 SP1
Date Tue, 26 May 2015 14:30:08 GMT
I have to admit that network created from the scratch works as expected. I could not reproduce
the issue. Some VM-s has to be re-crated from the scratch as well to be able to work at VPC
correctly. So I have resolved all the issues and will blame "HA", cause after hosts update
no VM-s were restarted. I used migration between hosts at runtime so update went without client
VM shutdown.

More tests shows that VR is totally broken.  I have created new isolated network with SNAT
and was not able to ping even VR public IP.  VM was not pinging as well.
From the other side VPC networks are working correctly.  Can someone answer the question --
which way those VM-s are different?

After upgrade we have a serious problem with VR for shared guest network. It seem everything
is working OK, but after a while we got these errors on system console:

Domain routerCommand: com.cloud.agent.api.Command failed while ...25 May 2015 16:58:08 Domain
routerUnable to restart r-30-VM which was running on hos...availability zone: ZoneX: Pod 1

After VR restart everything goes back for a while (~ 3-4 min) and then problem comes back.
VR is slow. Logging into VR from host for troubleshooting takes around 30 sec.  All the VM-s
in guest network are also slow because of the network. Network restart has failed. VR restart
does not give anything. Inside VR even simple tasks like "ps ax" or "top" take seconds.  

Do you have any ideas why that can happen?

Vadim.

We have tested upgrading to XS 6.5 SP1 with CloudStack 4.5.1 and we didn't run into any issues.
We tested the following without any problems:

Start of existing VM
Deploy VM
Destroy VM
Attach ISO
Detach ISO
Snapshot of VM
Live migration of VM to another host
Storage migration to another SR
Add NIC
Remove NIC

And probably some other stuff that i don't remember right now.
