Can you please provide more details - what's slow (time to boot? time to open xterm), can you measure network IO / block IO ? Please upgrade to newer host/guest as well rhel6.2/rhel5.8. Try using virtio devices in the guests. Maybe your original image has issues? Please try to install a fresh image. Hi davidyangyi, Any update of comment #2 ? Closing, no replies from the reporter, and otherwise, we are not aware of such issue. |
Created attachment 564559 [details] template deployment.0 Description of problem: I use rhel6.1 as qemu-kvm host. using opennebula2.2 I set up rhel5.3/5.5/5.6 guests. But the rhel5.x guests are running very slow. While I set up another rhel6.1 guest, it is running fast as normal. Version-Release number of selected component (if applicable): Host: Red Hat Enterprise Linux Server release 6.1 (Santiago) Guest: Red Hat Enterprise Linux Server release 5.6 (Tikanga) How reproducible: Steps to Reproduce: 1. use virt-manager to install a rhel5.x.img with desktop 2. copy rhel5.x.img to disk.0 3. use deployment.0 to deploy 4. virsh create deployment.0 Actual results: Expected results: in virt-manager, open the one-7 domain, you can see login very slow and openning a term very slow too Additional info:
