4 months ago Running your host config in a VM doesn't reproduce the issue for me.
Can you double-check that the ZFS datasets have set xattr=sa and acltype=posixacl?
Your tmpfs / might be a tad small at 10%.
I would strace -f the virtiofsd next. There are a few more knobs that are not configurable yet; I recently added microvm.virtiofsd.inodeFileHandles.

mountpoint = "/nix";
options = {
acltype = "off"; # nix store is owned by root
};Seems I didn't have the mental power to doublecheck all shared dataset options. And I've read that warning inside the documentation at least 10 times too..
This is embarassing, sorry to waste your time.
Adding acltype = "posixacl"; xattr = "sa"; instead of acltype = "off"; was indeed the solution to my problem!

1 week ago Hello again, old me! I have made stuff just complex enough to hit this same issue.. but with a twist!
I expected the source of a dataset attribute to not matter. Dataset property inheritence would allow me to cleanly separate and minimize vm configuration into host + glue + guest config.
What actually happened was inconsistent results between bare metal ZFS and emulated ZFS (within a virtual machine). Operations not happening as root user on the share on the guest returns error code "Operation not supported" (for any operation like open_dir, create_file, remove_file, etc).
To fix, set the attributes acltype and xattr explicitly on each and every dataset you share with your vm(s)! This means your attributes source must be set to "local" when querying dataset properties.
[bert-proesmans@buddy:~]$ zfs get xattr,acltype storage/postgres/state/test
NAME PROPERTY VALUE SOURCE
storage/postgres/state/test xattr sa local # <---
storage/postgres/state/test acltype posix local # <---No idea why the property locality matters though.
Also, if you optimize multiple shares into a single mount folder; RAMfs doesn't support posix acl. A tempfs with remount read-only is workable.
The problem looks like below;
[bert-proesmans@test:/data]$ namei -l /data
f: /data
drwxr-xr-x root root /
drwxr-xr-x root root data
#^^^^^^^^^----------------- Any user should be able to open and read /data
[bert-proesmans@test:~]$ cd /data
-bash: cd: /data: Operation not supported
Hi, I'm building out a declarative microVM and it turns out there is an issue with some services that do not want to start within the VM. I've been researching symptoms for 8 hours but cannot find the culprit. At this point I'm still testing out what microvm entails, the referenced configuration is for a single hypervisor and a single vm to test the virtualization software and configuration options. The host is an AMD system; AMD Athlon 200GE + 16GB DDR3 + ~10GiB usable storage on ZFS.
The specific error for this topic comes from the systemd-networkd.service journal log inside the vm:
This seems to indicate that the binary is not found at the provided path, but other files and binaries appear to exist just fine. For example the debugging service "my-cool-user-service-start" executes just fine. The systemd-networkd binary file is there when I navigate the host filesystem, it's a ~2M binary file.
Since I don't really understand virtiofs I've tried giving the VM a GB more RAM but that did not resolve the issue. There are seemingly no (relevant) errors in the host's journal.
The configuration is derived from the "Declarative MicroVMs" + "A simple network setup" documentation pages, with shares on top of a ZFS pool with the purpose of serving technitium DNS.
