IDE is just as slow. Just over 2 hours for 2008R2 install. Is this what you mean by kvm? lsmod | grep kvm kvm_intel 54285 3 kvm 332980 1 kvm_intel *Steve Dainard * IT Infrastructure Manager Miovision | *Rethink Traffic* 519-513-2407 ex.250

Re: [Users] Extremely poor disk access speeds in Windows guest

I've reconfigured my setup (good succes below, but need clarity on gluster option): Two nodes total, both running virt and glusterfs storage (2 node replica, quorum). I've created an NFS storage domain, pointed at the first nodes IP address. I've launched a 2008 R2 SP1 install with a virtio-scsi

Re: [Users] Extremely poor disk access speeds in Windows guest

I notced updates on a Win7 VM I ceated previously were *really* slow, but when I logged in to it remotely for daily use, it seemed pretty snappy. I did not do any significant data transfers, however. I had the same latest virtio-win drivers installed, and in oVirt, the disk was of type VI

Adding the virtio-scsi developers. Anyhow, virtio-scsi is newer and less established than viostor (the block device), so you might want to try it out. A disclaimer: There are time and patches gaps between RHEL and other versions. Ronen. On 01/28/2014 10:39 PM, Steve Dainard wrote: I've had a b

Re: [Users] Extremely poor disk access speeds in Windows guest

I've had a bit of luck here. Overall IO performance is very poor during Windows updates, but a contributing factor seems to be the "SCSI Controller" device in the guest. This last install I didn't install a driver for that device, and my performance is much better. Updates still chug along quite s

I have two options, virtio and virtio-scsi. I was using virtio, and have also attempted virtio-scsi on another Windows guest with the same results. Using the newest drivers, virtio-win-0.1-74.iso. *Steve Dainard * IT Infrastructure Manager Miovision | *Rethink Traffic* 51
