Hello,

 

I set up a new VM and configured a Windows 10 ISO downloaded from Microsoft as the boot CD device. When the VM boots, I have the ability to press any key to get the CD to boot, and then the blue windows logo shows, but then the boot sequence halts there and I don't see a progress indicator, and the screen sticks on the windows logo.

 

I get this result whether I use a VNC GPU or a passthrough device. This VM does not have a virtual hard drive defined because I'm passing through an NVMe device for direct storage access. The log shows the following output:

Any ideas?

Actually, after ignoring it for several minutes, it did eventually boot to the CD drive. However, after running the install to the NVMe drive, the VM will not boot and just shows the BIOS prompt. Now what?

Reinstall using seabios instead of ovmf.
