Error message Error Domain=VZErrorDomain Code=1 "The virtual machine failed to start." UserInfo={NSLocalizedFailure=Internal Virtualization error., NSLocalizedFailureReason=The virtual machine failed to start.} appears when following instruction on Intel Mac

Tried all the steps mentioned in README and getting

.build/TinyLinux.xcarchive/Products/usr/local/bin/TinyLinux --vmlinux ubuntu/vmlinux --initrd ubuntu/initrd --commandline "console=hvc0 root=/dev/vda1" --image ubuntu/ubuntu-20.04.3-live-server-arm64.iso

Try without ubuntu/ to kernel and ramdisk path.

.build/TinyLinux.xcarchive/Products/usr/local/bin/TinyLinux --vmlinux vmlinux --initrd initrd --commandline "console=hvc0 root=/dev/vda1" --image ubuntu/ubuntu-20.04.3-live-server-arm64.iso

As the pervious instructions described, ./ubuntu directory is a temporary one, just a mounting point to extract kernel and ramdisk to ./, and after umount, it doesn't hold anything.
I also updated README.md as 59d342a to clarify it.

I mounted on test folder and placed them under ubuntu folder and gave the path from there. So that doesn't seem to be the issue.The paths are correct and still getting the above error. I am on macOS x86_64 does that matter in this case ?

[amit-bst]

Things are discussed here. evansm7/vftool#2 But its not clear. I just want to boot ubuntu desktop iso file using virtualization.framework.

Please read the instruction carefully, the one written in README is for Apple Silicon (M1, arm64) mac.

You need to modify it for your x64 mac.

[amit-bst]

Do, I need to download the x86_64 image of ubuntu and try the same steps will it work ?

[niw]

Yes, it may not be exactly same, but mostly same. Download x64 version of iso like normal Ubuntu Desktop iso and follow same steps. You don't need to ungzip, and can use vmlinuz bzImage file as-is.

@niw thanks a lot mate. I was able to boot amd64 ubuntu desktop from the advice you gave me. Thanks, much appreciated!!

[niw]

Glad to hear that you could boot Ubuntu up. I also updated README to mention about x64 mac usage.
I will close this issue now.
