Independent of the planned tracker transition: this issue would require more information by original reporter anyway.
>From the information provided so far, I cannot reproduce this problem, and the error messages don't look like common misconfigurations on host side like wrong permissions, AppArmor policies or something like that. Especially the error message "Cannnot allocate memory" looks weird to me. So I think there should at least be more details about the host system this was deployed on. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1673957 Title: virtfs: mapped-xattr on mount point Status in QEMU: Incomplete Bug description: With -virtfs local,path="/tmp",security_model=mapped-xattr,mount_tag="shared2" in the qemu command line, shared2 on /mnt/testbis type 9p (rw,sync,dirsync,relatime,trans=virtio,version=9p2000.L,msize=262144) in the guest mount points, and tmpfs on /tmp type tmpfs (rw,nosuid,nodev) in the host mount points (with CONFIG_TMPFS_XATTR=y according to zgrep /proc/config.gz), running qemu as user "vm-test", trying to "touch a" in /mnt/testbis on the VM fails with "Operation not supported". In addition, no file or directory actually present in the host's /tmp can be seen in the guest's /mnt/testbis. When trying to replace "/tmp" with "/tmp/aaa" on the host, with /tmp/aaa owned by root:root, still running qemu as vm-test, trying to run "ls" in the guest's /mnt/testbis fails with the weird "ls: reading directory '.': Cannot allocate memory", while the directory is empty. After a "chown vm-test /tmp/aaa", the guest can list the files (despite the permissions already allowing it to do so before), but still not write new files: "cannot touch 'b': Operation not supported". Do you have a pointer as to what is happening? PS: complete setup is running all this inside a qemu VM that I use for testing, I guess it shouldn't matter but saying it just in case To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1673957/+subscriptions
