.... We investigated these problems. 1) It takes time to recognize the exchange of CDROM. The problem that it takes time for recognition is to wait intentionally on the qemu-dm side. ・tools/ioemu/xenstore.c 314 void xenstore_process_event(void *opaque) 315 { ... 343 if (image[0]) { 344 media_filename[hd_index] = strdup(image); 345 xenstore_check_new_media_present(5000); << This 346 } The processing recognized after it waits for five seconds is executed. We think that this waiting is unnecessary after exchanges CDROM. Why do you wait for five seconds before CDROM recogni...

Please see the three patches that fix the ACPI AML and QEMU race. They have been Ack-ed by both George (for inclusion in Xen 4.3) and by Stefano. They should be candidates for back-port in older hypervisors. Konrad Rzeszutek Wilk (3): piix4acpi, xen, vcpu hotplug: Split the notification from the changes. piix4acpi, xen: Clarify that the qemu_set_irq calls just do an IRQ pulse.

Hey Ian and Stefano, Please see this thread: http://lists.xen.org/archives/html/xen-devel/2013-05/msg01053.html for the debug patches and some of the discussion. These three patches fix an race that has been in QEMU traditional for a long time. The guts of the bug is that if you have a guest with these options: vcpus=1 maxvcpus=32 and do ''xl vcpu-set <guest> 32'' the

The following series of 10 patches is a merge of the xenfb and xenconsoled functionality into the qemu-dm code. The general approach taken is to have qemu-dm provide two machine types - one for xen paravirt, the other for fullyvirt. For compatability the later is the default. The goals overall are to kill LibVNCServer, remove alot of code duplication and/or parallel impls of the same concepts, and
