Adam,
Same crash with just one vm. Yes, -cpu host. Intel 12th Gen i3-1220P
Can you send me (to my personal email) an exportpack of your setup? You can create the exportpack in your build directory with
make exportpack EXPORTPACKTARGETDIR=/path/to/dir E=<YOUR_ENTRY>
Then archive /path/to/dir and send it to me please.
Best, Matthias.
Richard

Hi Richard,
is it working with just one VM? And is it QEMU with "-cpu host"? And if yes, what's the host CPU if I may ask?

Adam,
I did another ham sync, rebuilt fiasco, rebuilt l4, rebuilt my natives, and it's a little better? Now the VMs crash, but at least the system keeps running and I can seem my natives printing even after both VMs are halted. So at least the whole system doesn't crash any more. Just the VMs.
Again, yes, Debian Linux on QEMU with kvm and six cores. Cores 0 and 1 are for L4 and natives, cores 2 and 3 are for vm1, cores 4 and 5 are for vm2.
Please see attached!

Richard,
is that setup running on Linux QEMU+KVM? If yes, we recently (really a few days ago) fixed an issue in this virtualized setup (wrt to performance counter handling). It's on GH since Friday I believe. Otherwise please provide me you fiasco binary, such that I can look up fffffffff006a176 as this will point to the location that triggered the issue.
Thanks, Adam

Adam,
So I have been using version 23.10.1, built as per the download page, and have gotten a couple VMs to ping eachother and give me a login prompt. I finally realized I was missing the virtio_switch package and grabbed it from github and put it where it is supposed to go. Of course, being a version mismatch now, it did not compile. I decide to bite the bullet and do an upgrade (always a mistake) and use the new build process given with the new website. That went smoothly! I install ham, run it, etc, everything builds, I update my local scripts and links to use the new environment variables instead of being hardcoded, and it all builds and looks good. Except that it doesn't run. The VMs get a memory exception and kick into jdb.
I have not changed any of my .cfg or .list files. The VMs and ramdisks are untouched. My local (L4 native) processes start and appear to run. But the VMs crash for some reason. Even the device tree is unchanged. I also tried a newly built linux (as opposed to a prebuilt) and that failed as well.
Is there some reason for this new crash between version 23.10.1 and the latest version from github? I've attached the VM startup output from both the old and new runs so you can take a look.
I'm so close... I see the IP configuration parameter and how to set up lwip and virtio_switch.... Then my natives should be able to talk directly to my linuxes.
Your help is greatly appreciated!
