Users, I am facing a problem with one client running a VPC on my HVM-backed CloudStack 4.5.2. The machines behind the VR get poor ping times and slow transfers. I think the issue is the Intel network adapter driver... Typically I setup Windows VM's with Windows PV as the OS type and add the drivers in myself. That did not happen and now they have a production environment running the generic Intel driver.
Anyone know how to get a standard instance setup /w the additional drivers so I can switch it over to Windows PV OS type? I think using the Red Hat VirtIO drivers will help resolve the problem. Any suggestions for converting a Windows instance to Windows PV? If I just switch the OS will not boot... Any known issues with the VPC VR and general slowness? I see between 50M ~ 100M max throughput and really wild latency between 10ms -> 200ms across the 1000mbits data center LAN. Would the default Intel driver explain some of these troubles? Thanks in advance for any guidance you can provide, Dustin
