[Xen-ia64-devel] [Test Report] Xen/IPF Unstable CS#19432 Status (Linux#806, ioemu#545882...) --- One block new issue
Hi, all Latest Cset#19432 has one block issue, I has checked it, found this issue should be related with the latest Qemu. New issue: === 1. VTI can not boot up with the latest Qemu With the latest qemu, VTI can not boot up on C/s 19432, xenU can boot up. If changed an old qemu(82787c6f689d8...), VTI can boot up successfully on C/s 19432.
