Hello, My Windows Instances are set to "Windows PV" and they are assigned the "virtio" controller for Root and Data disks in Settings.
However, inside the Windows Instance, I only see QEMU HARDDISKs and a Standard SATA AHCI Controller instead of any kind of VirtIO device. I am able to add new Volumes that initially appear inside the OS as VirtIO SCSI Disks but then change to QEMU HARDDISKs after a reboot. I have attempted to manually add the VirtIO drivers to these QEMU disks and to the Standard SATA AHCI Controller with no success. I attempted to add the drivers during installation but the disks always change to QEMU HARDDISK after a reboot. I added a new Volume to the Instance to see if the VirtIO drivers would be added with a new Volume without success. I ran CrystalDiskMark benchmark tests on different Instances with the different root and data disk controllers (ide, scsi, virtio, and osdefault) and the benchmark tests all came back roughly the same. Basically, I am not seeing that my specific CloudStack/KVM setup is honoring the Root and Data disk Settings for these Windows Instances and want to figure out what I can do to fix this issue please. Thank you for the help, Jordan -----Original Message----- From: Wei ZHOU <[email protected]> Sent: Tuesday, July 23, 2024 10:09 AM To: [email protected] Subject: Re: Root Disk Controller Global Setting EXTERNAL for vms on kvm, the disk controller (virtio/ide/virtio-scsi) is determined by os type. It can be overwritten by vm settings. Users can change os type for each vm as another option. If you have Windows vm with virtio driver installed, you can change the the OS type to "Windows PV". IMO, It is not needed to have global settings for kvm vms, which will bring more trouble than benefits. If the value in global settings is not supported by the vm(e.g. driver is not installed), vm won't boot up. -Wei On Tuesday, July 23, 2024, Jordan Wolfson <[email protected]> wrote: > Hello, > > Thank you, but I am asking about a Global Setting that can be enabled > or disabled.
