It looks to fail when launching a guest, and the
http://www.chiark.greenend.org.uk/~xensrcts/logs/17323/test-amd64-amd64-xl/field-cricket---var-log-xen-console-guest-debian.guest.osstest.log

tells me:


0.823327] Write protecting the kernel read-only data: 12288k

mount: mounting none on /dev failed: No such device

[   89.071074] 
vcpu 0

So is it that the kernel needs to have CONFIG_DEVTMPS=y ? Or perhaps
CONFIG_SYSFS_DEPRECATED_V2? Or CONFIG_SYSFS_DEPRECATED?

Not really sure what is needed for this?
