AFAIK, no one has been working on this. But you could try a recent version of `qemu` on macOS. In January or so, Hypervisor framework based acceleration was added.

hyperkit currently does not support snapshotting and I'm not aware of any effort to support it.

some 4+ years ago we had Windows Nano Server (is that still a thing) booting on hyperkit but I can't remember how much hacking was required for that. I think...

what kind of system are you running this on?

Locally `make test` works. The CI seem to have failed on extracting the tinylinux initrd or to create a modified initrd from it after massaging it. I've re-kicked CI to...

scrap the above, the `cpio` message seem to be warning, the real error is: ``` spawn ../build/hyperkit -A -m 512M -s 0:0,hostbridge -s 31,lpc -l com1,stdio -s 1:0,ahci-hd,/dev/rdisk3 -f kexec,./vmlinuz,./initrd.gz,earlyprintk=serial...

Add a `sysctl machdep.cpu` to https://github.com/moby/hyperkit/pull/329 and on the CI machine I get: ``` machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV...

not using the latest CircleCI environment, ie the original 11.3.1, seems to work (fails later with opam errors, but that is separate). triaging through the xcode versions from https://circleci.com/docs/2.0/testing-ios/ -...

@jhowardmsft the kernel config is at https://github.com/linuxkit/linuxkit/blob/master/kernel/config-4.19.x-x86_64 I don't think there were any significant changes recently to the config file.

Thanks for the triage. The LinuxKit changes themselves are very unlikely candidates. More likely is that some code in the Linux kernel itself changed. I did a quick scan through...
