[Qemu-devel] [Bug 1459622] [NEW] firefox hang with virtfs

[Tom Yan]

Public bug reported:

Firefox hangs once it starts to load pages. I tried to delete
.cache/mozilla/ and .mozilla/ but it doesn't help. But if I mount tmpfs
on to .mozilla (not necessary for .cache/mozilla/), pages loads fine.

I started the vm as root (sudo) with the following command: qemu-system-
x86_64 -enable-kvm -m 4G -virtfs
local,mount_tag=qemu,security_model=passthrough,path=/mnt/qemu/ -kernel
/mnt/qemu/boot/vmlinuz-linux -initrd /mnt/qemu/boot/initramfs-linux-
fallback.img -append 'rw root=qemu fstype=9p' -usbdevice tablet -vga qxl
-spice port=12345,disable-ticketing

/mnt/qemu is a btrfs snapshot of the subvolume used as the host root

Arch Linux, qemu 2.3.0, firefox 38.0.1

Same situation here:
Firefox can't handle ~/.mozilla to be a virtio-9p mount.
Here the subvolume is ext4, mounted only at /home.

I also noticed that chromium is working, but it complains about some errors:
getrlimit(RLIMIT_NOFILE) failed

Looking through old bug tickets... can you still reproduce this issue
with the latest version of QEMU? Or could we close this ticket nowadays?
