| * xm reboot: Fix wait option of xm reboot commandKeir Fraser2008-02-071-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I rebooted a domain by xm reboot command with wait option, I saw the following message. But, rebooting the domain succeeded. Domain vm1 destroyed for failed in rebooting The cause why the message was shown is the domain is destroyed temporarily by processing of xm reboot command. The domain information is not gotten from Xend by server.xend.domains() function till recreating the domain is completed. This patch fixes processing of xm reboot command in Xm side. It waits just a bit till recreating the domain is completed, then it measures the success or failure of the reboot of the domain. Signed-off-by: Masaki Kanno <kanno.masaki@jp.fujitsu.com>
| * ioemu: avoid name clashes due to LIST_* macrosKeir Fraser2008-02-075-48/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is what I wrote in my submission to qemu upstream: qemu's audio subdirectory contains a copy of BSD's sys-queue.h, which defines a bunch of LIST_ macros. This makes it difficult to build a program made partly out of qemu and partly out of the Linux kernel[1], since Linux has a different set of LIST_ macros. It might also cause trouble when mixing with BSD-derived code. Under the circumstances it's probably best to rename the versions in qemu. The attached patch does this. [1] You might well ask why anyone would want to do this. In Xen we are moving our emulation of IO devices from processes which run on the host into a dedicated VM (one per actual VM) which we call a `stub domain'. This dedicated VM runs a very cut-down `operating system' which uses some code from Linux. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

| | | | | | | | | | | | | | | | | | | | | | | | Here is what I wrote in my submission to qemu upstream: The patch below makes it possible to disable AF_UNIX (unix-domain) sockets in host environments which do not define _WIN32, by adding -DNO_UNIX_SOCKETS to the compiler flags. This is useful in the effectively-embedded qemu host which are going to be using for device emulation in Xen. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* | [IA64] Fix domain refernece countingAlex Williamson2008-02-051-14/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the domain refernece counting caused by allocated pages from domheap for shared page and hyperregister page. Calling share_xen_page_with_guest() with domain heap page is wrong so that it increments domian->xenpages which is never decremented. Thus the domian refcount doesn't decrease to 0 so that destroy_domain() is never called. This patch make the allocation done from xenheap again. The other way to fix it is to work around domain->xenheap and the page refrence count somehow, but it would be very ugly. The right way to do so is to enhance the xen page allocator to be aware of this kind of page in addition to xenheap and domheap. But we don't want to touch the common code. And given that the limitation on xenheap of xen/ia64 is much relaxed, probably it isn't necessary to be so nervouse not to allocate those pages from xenheap. If it happend to be necessary to allocate those pages from domheap, we could address it at that time. For now just allocate them from xenheap. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp>

| * ioemu: use SIGHUP instead of SIGKILLKeir Fraser2008-02-041-1/+1
| | | | | | | | | | | | | | | | | | | | The stub domain device model needs to trap the termination signal so as to actually destroy the stub domain. SIGKILL can't be trapped, SIGTERM is caught by SDL and so may be unnoticed. SIGHUP can be trapped and is not caught by SDL (and by default causes a process termination without core).

| | | | | | | | | | | | | | | | | | | | | | The save failure cleanup introduced in 13543:207523704fb1 is incorrect: if we didn't get as far as actually suspending the domain, then the guest domain will not be expecting the devices to be removed (seen on both Linux and Solaris, which don't expect a 'Closing' state when they hold the device open). Only re-jig devices if we definitely shut the domain down. Signed-off-by: John Levon <john.levon@sun.com>
| * hvm: Fix 'xm save' bug in qhich qemu-dm ignores SIGTERM.Keir Fraser2008-02-011-2/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When saving a guest in early ChangeSet (Before 16750), Xend will send "SIGKILL" signal to kill qemu process. But in ChangeSet 16750, the signal is modified to "SIGTERM". However, "SIGTERM" handler has been registered by SDL in qemu. So when qemu process receives a "SIGTERM", SDL will catch it and it will push out a "SDL_QUIT" even to qemu. If qemu can receive that event, it will be successfully terminated. While we do "xm save", qemu can't go out from the dead loop "while (suspend_requested) {...}" in main_loop() to handle the SQL_QUIT event. So it is unable to poll that "SDL_QUIT" event. This makes xm save command hang. This fix enables qemu to poll the "SDL_QUIT" event while doing save. Signed-off-by: Xu Dongxiao <dongxiao.xu@intel.com>

| * Direct Linux boot: XenD changes for HVM direct Linux boot.Keir Fraser2008-02-013-6/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides the tools support for direct kernel boot of HVM guests. Currently the config files in /etc/xen support the args 'kernel', 'ramdisk' and 'extra'. For PV guests these have the obvious meaning. Unfortunately HVM guest configs hijacked the 'kernel' parameter and use it to refer to the path of the HVM firmware. So, this patch adds a new config file parameter called 'loader' which is used to refer to the HVM firmware instead. The conventions for loading the initrd image say that it should live at the end of memory. This requires QEMU to know the size of the guest's initial RAM allocation, so image.py is changed to pass the '-m' flag to QEMU. The HVMImageHandler class in image.py is changed so that if the 'kernel', 'ramdisk' or 'extra' params were given in the config these are passed to QEMU with the '-kernel', '-initrd' and '-append' flags respectively. Finally, the 'loader' param is used as the arg to 'xc_hvm_build' instead of the old 'kernel' param. For the sake of compatability with old HVM guest config files, if the config file has a 'kernel' param whose path matches that of the HVM firmware, then we automatically convert this 'kernel' param into the 'loader' param. This ensures existing HVM guests work without changes required. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
| * Direct Linux boot: Support booting non-relocatable Linux kernels.Keir Fraser2008-02-011-2/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces a hack to make non-relocatable kernels bootable too. Non-relocatable kernels absolutely want to run at 0x100000 and are not at all happy about being at 0x200000. Fortunately, thanks to crazy programs like LOADLIN, Linux has a couple of hooks in its boot process which can be used to play games. The 'code32_switch' hook is executed immediately following the switch to protected mode. So, this patch installs a hook at 0x200000+kernel_size. The hook is hand crafted assembly which sets up all the segments as needed, then essentially does memmove(0x100000,0x200000,kernel_size) and finally does an unconditional jmp to 0x100000. Amazingly this actually really does work. It has been successfully tested with RHEL-2.1 and Fedora Core 6 install kernels on i386, and Fedora Core 6 and 7 kernels on x86_64. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
| * Direct Linux boot: Support booting relocatable Linux kernels.Keir Fraser2008-02-011-88/+266
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the basic infrastructure for direct kernel boot in the ioemu copy of QEMU. The current #ifdef disabled code is actually obsolete wrt to upstream QEMU code. So this is removed entirely. In its place I have imported the latest upstream QEMU code. The QEMU code assumes that the guest RAM is directly mapped into the QEMU process, so there were some changes neccessary. Instead of strcpy/memcpy'ing the args and kernel header into guest RAM, cpu_physical_memory_rw is used. Intead of fread() the initrd and kernel into guest RAM a helper function is used fread2guest which reads into a small buffer and then uses cpu_physical_memory_rw. NB in reading the following, Documentation/i386/boot.txt is a useful reference for what's going on. Next, instead of loading the kernel at 0x100000, this code loads it at 0x200000. This is far enough away that there's no risk of it overlapping with the HVM firmware image. If the Linux kernel boot protocol is 0x205 or later, and the flag at offset 0x234 in the kernel header is 1, then the guest kernel was built with CONFIG_RELOCATABLE=y. In this scenario we merely need to tell the kernel what address it has been relocated to by writing 0x200000 into the kernel header at offset 0x214. When switching from real mode into protected mode the kernel will immediately start executing at 0x200000 and be happy with life. This should work for 2.6.20 or later on i386, and 2.6.22 or later on x86_64. This has been verified with Fedora 7 and Fedora 8 bare metal kernels on i386 and x86_64 from the $TREE/images/pxeboot of the install trees. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
