@iamwill, are you sure you are using a qemu kernel that supports btrfs?

@CurlyMo, I am now, I did some more research and found qemu-env from xbianonpi here and it gets past the first kernel panic but now I'm running into another problem.

Terminal

qemu-system-arm -initrd qemu-env-master/initramfs.gz -hda xbian.img -cpu arm1176 -M versatilepb -m 256 -net nic -kernel qemu-env-master/zImage -serial stdio -append "rw bcm2708_fb.fbwidth=1280 bcm2708_fb.fbheight=1024 dwc_otg.lpm_enable=0 kgdboc=ttyAMA0,115200 console=tty1 root=LABEL=xbian-beta2,autodefrag,noatime,relatime,compress=lzo rootfstype=btrfs rw rootflags=subvol=root/@,autodefrag,compress=lzo sdhci-bcm2708.sync_after_dma=0 dwc_otg.lpm_enable=0 rootwait"

That is how I am running it now, and it seems to recognize btrfs now but it isn't properly mounting sda2. Again, mmcblk doesn't work at all. (I did change the "root=LABEL=xbian-beta2" because when booting with "LABEL=xbian-root-btrfs" it didn't recognize the label. Here is a screenshot of where I am getting stuck now...

Thanks again for the help.
