Hi, just to let You know, with realtek instead of virtio-net, it seems to be reachable for almost three days.. I'd give it another day, then we can be pretty sure it's virtio related...

Re: windows 2008 falling asleep under KVM
Hello Gleb, please note, it's windows 2008, not windows8, not sure whether there's some significant difference, though.. Disable device powersave: - Control Panel - Network Internet - Network Connections - Right-click on desired interface, and select Properties - Click the Configure button on the interface properties - Under the Advanced tab, look for power-saving related options and set to Disabled - Under the Power Management tab, uncheck Allow computer to turn off this device to save power - Save Reboot I forgot to mention that, I'm using virtio network driver, and it doesn't seem to support any power managemt (which is not surprising I guess) In addition: - Control Panel - Hardware Sound - Power Options there's no sound card there.. - Select High performance done already. - By the selected power profile, select Change Plan Settings - In the Edit Plan Settings, select Change advanced power settings - See if there is something relevant to network connection there and if yes change it to not sleep everything was already disabled... - Save Reboot maybe I should try using realtek network device instead of virtio?

windows 2008 falling asleep under KVM
Hello, I'm trying to solve strange issue with windows2008 VM under KVM. It seems to be somehow falling asleep after some time, becoming unreachable over network. However connecting to qemu VNC immediately makes windows reachable again... I wonder whether this is the same issue? http://lists.nongnu.org/archive/html/qemu-devel/2013-03/msg02278.html I've tried disabling HPET, same result. I'm using qemu-kvm 1.4.0, seabios 1.7.2.2, kernel 3.0.82 with kvm-kmod-3.8, x86_64 centos6. Any idea what should I check? Thanks a lot in advance with best regards nikola ciprich -- - Ing.
