When I mount a 9pfs filesystem in guest with no write permission for some dirs, I'm getting strange errors in guest.
Host (as a regular user): qemu-system-x86_64 -virtfs local,path=/,security_model=mapped-file,mount_tag=tag Guest: # mount -t 9p -o trans=virtio,ro tag /mnt # ls /mnt ls: reading directory /mnt: Unknown error 593 # ls /mnt/dev ls: reading directory /mnt/dev: Unknown error 849 # ls /mnt/tmp [works] # ls /mnt/root ls: cannot open directory /mnt/root: Permission denied So, it reports errors while trying to _read_ (not open) readable but non-writable dirs, and these errors are _random_. It correctly reports errors when trying to open an unreadable dir. This is 1.4.0. Similar problem exists with earlier versions of qemu. Thanks! /mjt
