Hi, First of all please allow me to salute the community since this is my first post. Now my problem. I have been using KVM to conduct tests for various software on windows, so far it worked out just fine. I use savevm and loadvm to assure that the VM is in the same state for each test. I do a savevm manually, then start the automatic tests. Lately i was trying to optimize parts of my tests, to increase the throughput. First the network I/O was slow with the default device, and i needed to copy some files to the VM for each test. The virtio network driver was fast, but with my bridge networking, on Win XP, after starting the VM with loadvm. This isn't such a big issue since i then started using e1000 device, and speed increased. I am not sure just how much would virtio be faster, so the question remains : Doesn't virtio work with loadvm/savevm, or (most probably) am i doing something wrong? The second issue, even a greather one, is disk access speed in the VM. Again i have looked at virtio, but it seems that there is no Win direver. Is that so? What can i do to improove disk access performance? The final issue isn't related to performance. With the e1000 device, accessing or writing files on a samba share from the host failes saying that the file doesn't exists, (the file exists, i am sure). This doesn't happen all that often, less than 1% of the time, but it's rather anolying because it influences the tests. it seems to be happen randomly, i caoudm't identify a factor that might be causing it. Thank you in advance for your advices. -- Alpar Torok -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
