Just started recently. All but one of my kvm systems now experience a long boot delay, maybe close to a minute with the SeaBIOS version and Machine UUID on the screen.
There's an OpenBSD system, a Windows system, and several Linux systems that have been working fine for a long time and now experience this issue. Oddly enough one of my Linux kvm's still boots without extra delay.
Systems seem to work normally once booted.

Re: kvm boot delay
I have same issue. VMs started before without delay. Now is a time, from a start of VM till begin of boot approximately one minute. After booting, VM work fine. I readed on internet, that there can be something between MB and VGA and UEFI. Some days ago i replaced VGA. I checked logfiles of KVM and OS and there aren't any error messages. I haven't idea what can be problem.darkphader wrote:Just started recently.

The issue seems to be the presence of a cdrom device. When I remove the cdrom device, my VM starts and boots quickly.
Out of my 4 Windows 10 Pro VM's (all boot in BIOS mode) only one had a CDROM and removing it did "fix" the slow boot. I tried adding a CDROM to the others and then removing it but it didn't help.
The 3 Windows 11 Pro VM's all boot in UEFI and have no substantial delay. Out of my 2 Linux VM's neither has a delay now but one did have it and then one day its delay went away.
