Best approach to installing Windows 20xx VM on Cloudstack with KVM hypervisors based on EL8.8 #10553

I was wondering if it is best to select Windows PV at the list of operating systems for the VM while creating it or go with the actual windows 20xx (2019-2022-2025) OS name and install drivers during setup following the method outlined here. (method known as F6 drivers) |

Use the "Windows PV" profile, it will give you the best performance as it presents virtio devices. After the installation has succeeded, attach virtio-win again and run the setup.exe or whatever it is called so it will install all the other virtio drivers as well (for network, display etc). For Windows it is recommended to set video ram to 32MB or more and set the video card to QXL, this is done from the VM settings (with the VM shut down). This can also be set in the template settings and will be inherited by all the instances. HTH |

Awesome, thanks! Do you think for windows it is better to go with UEFI secure or UEFI legacy boot? I prefer legacy in case I need to talk to the ntfs through another boot session in case OS dies but that may sound too old school. Regarding the virtio-win.iso, since I can see the disk during setup (because of the PV selection), I guess it is not needed. Only after OS completes. |

secure boot or legacy both work with Windows 11. |

when you get to the disk and drivers section, detach the Widows ISO in Cloudstack and attach the virtio-win.iso, load the appropriate drivers. Then detach virtio-win.iso and attach the Windows.iso again.
