* xc_map_foreign_pages(), a convenient alternative to xc_map_foreign_batch()kfraser@localhost.localdomain2007-09-071-1/+1
| | | | | | | | | xc_map_foreign_batch() can succeed partially. It is awkward to use when you're only interested in complete success. Provide new xc_map_foreign_pages() convenience function for that kind of use. Also convert two obvious calls to use it. Signed-off-by: Markus Armbruster <armbru@redhat.com>
* [HVM] Control qemu's state-save via xenstore, instead of SIGUSR1Tim Deegan2007-07-241-27/+6
| | | | | | | This lets us verify that qemu has indeed stopped processing before we start saving guest memory. Also allow qemu to continue processing after the save has happened, instead of exiting immediately. Signed-off-by: Tim Deegan <Tim.Deegan@xensource.com>
* hvm: Re-introduce LPT1 device in ACPI tables.kfraser@localhost.localdomain2007-07-111-5/+0
| | | | | | | | | Once the presence of LPT1 is baked into a Windows guest, it gets upset if it is subsequently removed. Hence we add the 'LTP1' device object back into the ACPI DSDT, and remove IRQ 7 from the list of IRQs usable by the PCI-ISA links. Signed-off-by: Keir Fraser <keir@xensource.com>
* hvm: Fix ioemu Qcow support.kfraser@localhost.localdomain2007-06-201-0/+12
| | | | | | | | | | | | | | | | | | | | | | Normally by default, SIGUSR2 is not blocked, so the signal masks of SIGUSR2 in all threads is unblocked. When creating HVM guest, if we use the Qcow format image file, in the main thread, Qcow uses SIGUSR2 to be notified of the completion of the request after it issues an AIO request; in tools/ioemu/block.c: bdrv_read_em(), in some point between bdrv_aio_read() and qemu_aio_wait(), Dom0 may send a SIGUSR2 to Qemu immediately to indicate the completion of an AIO request -- since at the moment SIGUSR2 in main thread is blocked by qemu_aio_wait_start(), the signal may be delivered to one non-main thread, causing the signal handler of SIGUSR2 is invoked, then the main thread hangs in qemu_aio_wait()->syswait()... This patch blocks SIGUSR2 at the beginning of Qemu's main(), so it ensures SIGUSR2 is blocked by default when a new thread is created, then only the threads that use the signal unblock it.

| | | | | | | | | or uuid via xend logs, less unique than pids to prevent excessive number of log files hanging around, yet not immediately reused (unlike e.g., after domain crash or reboot) where previous log file is immediately overwritten. Not using domain names in logs avoids and chance of unprintable charcatres becoming embedded in filenames. Signed-off-by: Keir Fraser <keir@xensource.com>

* Use name instead of pid in QEMU logs.kfraser@localhost.localdomain2007-06-041-4/+6
| | | | | | | | | | | Change the logfile name generated by qemu-dm to use the pattern qemu-dm-[NAME].log instead of qemu-dm-[PID].log. This makes it easier for the adminsitrator to figure out which log corresponds to which guest (particularly after a crash where you no long know what PID the qemu-dm process for your guest had). It also prevents the number of log files from growing unbounded. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
* hvm: Exceed maximum number of ioemu's NIC for VNIF.kfraser@localhost.localdomain2007-05-311-23/+23

* ioemu: Attempt to setup tap interface up to 3 times.kfraser@localhost.localdomain2007-05-241-2/+4
| | | | | | | | | | | | | | | | As there is a (small) chance that vl.c:tap_open() fails (due to some sort of race-condition in the Linux kernel, which is noted as a bug in the source .../net/core/dev.c), we should attempt it again a couple of times if it doesn't succeed on the first attempt. I think three times in total is sufficient to avoid the problem. If tap_open() fails, qemu-dm will exit, which means that the domain dies - which is not such a good thing when attempting to restore a saved domain [of course, it would be even worse if it started, but didn't have networking - because there may not be a way to shut it down cleanly without network].

* [hvm] Keep track of time offset between domain time and dom0 time.Christian Limpach2007-04-031-0/+3
| | | | | | | | | | On each rtc time update from the hvm domain, we send an ioreq request to qemu which then updates the time offset xenstore entry. The time offset is preserved across reboot and can be set on domain creation by setting the rtc_timeoffset variable in a config file.

| * [HVM] qemu: Add guest address-space mapping cache.kfraser@localhost.localdomain2006-12-071-23/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | On IA32 host or IA32 PAE host, at present, generally, we can't create an HVM guest with more than 2G memory, because generally it's almost impossible for Qemu to find a large enough and consecutive virtual address space to map an HVM guest's whole physical address space. The attached patch fixes this issue using dynamic mapping based on little blocks of memory.
