But qemu can exit properly. Is it because "hlt" instruction is not emulated? Or other reason? Any hint to fix it? Thanks, Lin Ming ^ permalink raw reply [flat|nested] 8+ messages in thread

There's no BIOS support in kvmtool. So ACPI is not supported. With "acpi=off", qemu can't really "poweroff" guest too. Run "poweroff" in qemu with acpi on. Will now halt.

Run "poweroff" in qemu with acpi off. Will now halt. [ 16.773539] sd 0:0:0:0: [sda] Stopping disk [ 16.775245] System halted. Will BIOS support be added in kvmtool in the future?

Yes, I expect that to happen eventually. Various patchsets have been started by multiple people to support SeaBIOS but there hasn't been a focused effort to push them forward.
