VirtFS accessmode
Hi all, I'm trying to share a folder between a host and a guest using VirtFS. The source is NAS mounted on the host and QEMU runs as unprivileged user. The only way for me to use the folder inside the guest is to set the access mode to 'squash' but all file operations are performed by the user running QEMU. If I ran QEMU as root, the passthrough mode works as exp...

[PATCH] 9p/trans_virtio.c: Fix broken zero-copy on vmalloc() buffers
...address when we read/write to vmalloc buffers, such as those used for Linux kernle modules. This causes QEMU to die printing: qemu-system-x86_64: virtio: trying to map MMIO memory This patch enables 9p-virtio to correctly handle this case. This not only enables us to load Linux kernel modules off virtfs, but also enables ZFS file-based vdevs on virtfs to be used without killing QEMU. Also, special thanks to both Avi Kivity and Alexander Graf for their interpretation of QEMU backtraces. Without their guidence, tracking down this bug would have taken much longer.

How to change virtfs/9p/v9fs umask
Hi there. My question is regarding virtfs/9p/v9fs [1], not sure what's the appropiate name :) Basically I have a KVM + libvirt server sharing a directory with a guest in mapped mode. It works fine, but the only issue is with the file permissions of the files created by the guest inside the host: -They are 0700 for dirs and 0400 for...
