I think so. Or you can (probably) uses extra = "foo" in your domain configuration file. You can tell if you've edited the right place from /proc/cmdline. I'd expect there would be some indication in dmesg that barriers were or were not in use , but I didn't look > > For experimentation it might be useful to attach an xvdb to > the domain > and use that as the write target, it'll allow easier > experimentation > with mount options, and as a bonus you won't keep hosing your > root > filesystem (which I imagine is getting pretty tedious...) > To be sure I understand: create a new lv, mount it, and use it as the > write target.

I had thought you were using it only in dom0 but the ambiguity here made me wonder. What I meant was to create a new LV in the dom0, edit the domain configuration to attach it as an extra disk (i.e. xvdb or whatever) and then to format/mount it from within the guest.

No worries if not - my google foo is decent. I expect backports.org has a reasonably recent Wheezy kernel which you could install or else I think the kernel is independent enough that a partial upgrade (i.e. add Wheezy to sources.list and "apt-get install <linux-image-foo>") would not pull in too much of Wheezy.
