| Thread-topic: | HVM domain with write caching going on somewhere to disk |
I just about have my PV block device drivers booting, except just before the login screen appears I get a message that the registry couldn't be written out. I'm pretty sure that this is because some data from the int13 interface provided by the qemu intel ide driver that has been written, hasn't actually made it to the block device (lvm volume in my case). I've noticed before that any changes made in a Windows HVM domain shortly before an 'xm shutdown' don't ever get written out... Anyway, is there a way to make sure that the qemu stuff doesn't do any write caching at all? Thanks James _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
