I have a KVM with Windows Server 2008R2. Everything runs normally however file copies will occasionally hang for multiple minutes. It happens for both local and LAN copies. The VM itself isn't frozen. RDP is still responsive and I can open applications and files. The Proxmox host is under light load. I've seen this happen with small and large copies (10MB-10GB)
The graphs for the VM don't reflect the hang. I see where the disk IO jumps for the copy but it doesn't drop to reflect a hang. I'm sure that it's hanging because it doesn't just jump to 100% complete when it resumes.
Running up to date proxmox 3.1 and latest virtIO disk drivers. RAID reports that all disks are healthy.
