[Xen-devel] blktap2 not working with xen-3.5 unstable
Hi, Tapdisk2 utility on xen-3.5 unstable (last changeset 20445) fails in "tapdisk_init_queue" with error code -22: #sudo ./tools/blktap2/drivers/tapdisk2 -n aio:/nfs/hd.img unrecognized child response Any ideas what changesets after #20445 fixes this problem. Thanks, Ashish _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
