If I start a VM, strace it's tapdisk2 and then send the VM a shutdown, the strace shows tapdisk2 hanging here: *sigh*, for anyone who finds this via google, tracked it down to a stupid error. Shouldn't be using tapdisk2 for accessing an iscsi device since it appears as a raw block device, after changing to using phy: things work properly. - Nathan _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
