Starting with a fresh XP SP3 install, I tried installing (in that order): 1. Latest version from hg 2. 0.10.0.134 from meadowcourt 3. 0.11.0.238 from meadowcourt Each time reverting to initial state via System Restore. The results were all similar: 1. Xentop shows no block activity 2. Unresponsive UI + bad speed when transferring files from Dom0 to VM 3. For small files (<5MB), the above problem doesn't occur 4. For file transfers from the VM to Dom0, the above problem doesn't occur as well 5. Stray Xen pci device #0 with no driver installed The same thing occurs with check RX checksum dis/enabled. I now suspect that something changed in the recent xen and/or kernel (since I'm running yesterday's snapshot) that's causing this. Or is my hardware at fault? Please tell me if I can be of help remedying this. > >> >> Liwei >> > _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
