Re: Windows Virtual Machine on Cloudstack KVM Platform
Yes, Windows guests can run perfectly fine/stable and fast on KVM - Instead of 'Windows XXX" version guest OS type, chose "Windows PV" when you register Windows ISO - this ensures all SCSI/NIC hardware is VirtIO (optimal performance), otherwise if you chose Windows XXX (2012, 2016, etc) - the hardware emulated by KVM is IDE controller, Intel e1000 NIC etc - completely unusable slow performance. - Ensure you add VirtIO drivers for SCSI disk controller inside Windows (during Windows Setup - just like any proprietary SCSI controller), so you can completely Windows setup on custom SCSI controller (RedHat VirtIO SCSI controller) - Later install NIC VirtIO driver - There you go Drivers you can download from Fedora site: (ISO file, so you can attach it during Windows deployment, just like in old days with proprietary scsi controllers) https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/ there is "latest" and there is "stable" -judge for yourself which one you want to use If you at some point start getting BSOD in Windows - it's 99% due to some bug in VirtIO drivers (happened with Win2008/2012, 4-5 years ago in my ex company - just upgrade VirtIO drivers with newer ones, sometimes RTFM the driver Release notes will also help :wink) Best, On Fri, 4 Jun 2021 at 04:11, Hean Seng wrote: > HI > > Is there anybody running Windows on Cloudstack KVM platform, is there any > performance issue ? > > For Cloudstack KVM, running Windows, how can I know is using VirtIO driver > or not ?

Windows Virtual Machine on Cloudstack KVM Platform
HI Is there anybody running Windows on Cloudstack KVM platform, is there any performance issue ? For Cloudstack KVM, running Windows, how can I know is using VirtIO driver or not ? Seems I not able to choose if to use VirtIO or not . Thank you. -- Regards, Hean Seng
