Raise your hand if you have a physical floppy drive in a computer you've powered on in 2015. Okay, I see we got a few weirdos in the audience. That's okay, weirdos are welcome here. Kidding aside, media change detection doesn't fully work, isn't going to be fixed, and floppy passthrough just isn't earning its keep anymore.

We now always send a JSON blob describing the migration file format as part of the migration stream. However, some tools built around QEMU have proven to stumble over this. This patch gives the user the chance to disable said self-describing part of the migration stream. To disable vmdesc submission, just add -machine suppress-vmdesc=on to your QEMU command line.

Check for the aes_key_wrap and dea_key_wrap machine options and set the appropriate KVM device attribute(s) to tell the kernel to enable or disable the AES/DEA protected key functions for the guest domain. This patch introduces two new machine options for indicating the state of AES/DEA key wrapping functions.

2014-12-11Add the "-semihosting-config" option.Liviu Ionescu
The usual semihosting behaviour is to process the system calls locally and return; unfortuantelly the initial implementation dinamically changed the target to GDB during debug sessions, which, for the usual arm-none-eabi-gdb, is not implemented. The result was that during debug sessions the semihosting calls were discarded. This patch adds a configuration variable and an option to set it on the command line: -semihosting-config [enable=on|off,]target=native|gdb|auto This option enables semihosting and defines where the semihosting calls will be addressed, to QEMU ('native') or to GDB ('gdb'). The default is auto, which means 'gdb' during debug sessions and 'native' otherwise.

into staging s390x/kvm: Several updates/fixes/features 1. s390x/kvm: avoid synchronize_rcu's in kernel ---------------------------------------------- The first patches change s390x/kvm code to issue VCPU specific ioctls from the VCPU thread. This will avoid unnecessary synchronize_rcu in the kernel, which caused a noticably slowdown with many guest CPUs. It speeds up all start/restart/reset operations involving cpus drastically. 2. s390-ccw.img: block size and DASD format support --------------------------------------------------- The second part changes the s390-ccw bios to IPL (boot) more disk formats than before. Furthermore a small fix is made to the console output of the bios. 3. s390: Support for Hotplug of Standby Memory ---------------------------------------------- The third part adds support in s390 for a pool of standby memory, which can be set online/offline by the guest (ie, via chmem). The standby pool of memory is allocated as the difference between the initial memory setting and the maxmem setting. As part of this work, additional results are provided for the Read SCP Information SCLP, and new implentation is added for the Read Storage Element Information, Attach Storage Element, Assign Storage and Unassign Storage SCLPs, which enables the s390 guest to manipulate the standby memory pool. This patchset is based on work originally done by Jeng-Fang (Nick) Wang. Sample qemu command snippet: qemu -machine s390-ccw-virtio -m 1024M,maxmem=2048M,slots=32 -enable-kvm This will allocate 1024M of active memory, and another 1024M of standby memory. Example output from s390-tools lsmem: ============================================================================= 0x0000000000000000-0x000000000fffffff 256 online no 0-127 0x0000000010000000-0x000000001fffffff 256 online yes 128-255 0x0000000020000000-0x000000003fffffff 512 online no 256-511 0x0000000040000000-0x000000007fffffff 1024 offline - 512-1023 Memory device size : 2 MB Memory block size : 256 MB Total online memory : 1024 MB Total offline memory: 1024 MB The guest can dynamically enable part or all of the standby pool via the s390-tools chmem, for example: chmem -e 512M And can attempt to dynamically disable: chmem -d 512M 4. s390x/gdb: various fixes --------------------------- * Patch 1 fixes a bug where the cc was changed accidentally. * Patch 2 adds the gdb feature XML files for s390x * Patch 3 Define acr and fpr registers as coprocessor registers. This allows us to reuse the feature XML files. * Patch 4 whitespace fixes # gpg: Signature made Mon 01 Sep 2014 12:53:39 BST using RSA key ID B5A61C7C # gpg: Can't check signature: public key not found * remotes/borntraeger/tags/kvm-s390-20140901: s390x/gdb: coding style fixes s390x/gdb: generate target.xml and handle fp/ac as coprocessors s390x/gdb: add the feature xml files for s390x s390x/gdb: don't touch the cc if tcg is not enabled sclp-s390: Add memory hotplug SCLPs s390-virtio: Apply same memory boundaries as virtio-ccw virtio-ccw: Include standby memory when calculating storage increment sclp-s390: Add device to manage s390 memory hotplug pc-bios/s390-ccw.img binary update pc-bios/s390-ccw: Do proper console setup pc-bios/s390-ccw: IPL from DASD with format variations pc-bios/s390-ccw Really big EAV ECKD DASD handling pc-bios/s390-ccw Improve ECKD informational message pc-bios/s390-ccw: handle more ECKD DASD block sizes pc-bios/s390-ccw: support all virtio block size s390x/kvm: execute the first cpu reset on the vcpu thread s390x/kvm: execute "system reset" cpu resets on the vcpu thread s390x/kvm: execute sigp orders on the target vcpu thread s390x/kvm: run guest triggered resets on the target vcpu thread Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2014-08-29curl: Allow a cookie or cookies to be sent with http/https requests.Richard W.M. Jones
In order to access VMware ESX efficiently, we need to send a session cookie. This patch is very simple and just allows you to send that session cookie. It punts on the question of how you get the session cookie in the first place, but in practice you can just run a `curl' command against the server and extract the cookie that way. To use it, add file.cookie to the curl URL. For example: $ qemu-img info 'json: { "file.driver":"https", "file.url":"https://vcenter/folder/Windows%202003/Windows%202003-flat.vmdk?dcPath=Datacenter&dsName=datastore1", "file.sslverify":"off", "file.cookie":"vmware_soap_session=\"52a01262-bf93-ccce-d379-8dabb3e55560\""}' image: [...] file format: raw virtual size: 8.0G (8589934592 bytes) disk size: unavailable Signed-off-by: Richard W.M.

2014-08-29block.curl: adding 'timeout' optionDaniel Henrique Barboza

The previous default timeout of 5 seconds will be used if this option is not present.

This commit adds a new command, '-dump-vmstate', that takes a filename as an argument. When executed, QEMU will dump the vmstate information for the machine type it's invoked with to the file, and quit. The JSON-format output can then be used to compare the vmstate info for different QEMU versions, specifically to test whether live migration would break due to changes in the vmstate data. A Python script that compares the output of such JSON dumps is included in the following commit.

Update how type 0 (bios info) structures are generated, as follows: - convert bios_characteristics field to uin64_t (instead of uint8_t[8]), as described in the current smbios spec (v2.8) - enable "virtual machine" bit in bios_characteristics_extension_bits - add command line option to enable "uefi supported" bit in bios_characteristics_extension_bits These updates should make this optional structure more useful when used with edk2/ovmf. Only pc machines >= 2.1 are affected, and only when a type 0 structure is explicitly specified on the command line.

2014-05-19block: optimize zero writes with bdrv_write_zeroesPeter Lieven
this patch tries to optimize zero write requests by automatically using bdrv_write_zeroes if it is supported by the format. This significantly speeds up file system initialization and should speed zero write test used to test backend storage performance. I ran the following 2 tests on my internal SSD with a 50G QCOW2 container and on an attached iSCSI storage. a) mkfs.ext4 -E lazy_itable_init=0,lazy_journal_init=0 /dev/vdX QCOW2 [off] [on] [unmap] ----- runtime: 14secs 1.1secs 1.1secs filesize: 937M 18M 18M iSCSI [off] [on] [unmap] ---- runtime: 9.3s 0.9s 0.9s b) dd if=/dev/zero of=/dev/vdX bs=1M oflag=direct QCOW2 [off] [on] [unmap] ----- runtime: 246secs 18secs 18secs filesize: 51G 192K 192K throughput: 203M/s 2.3G/s 2.3G/s iSCSI* [off] [on] [unmap] ---- runtime: 8mins 45secs 33secs throughput: 106M/s 1.2G/s 1.6G/s allocated: 100% 100% 0% * The storage was connected via an 1Gbit interface. It seems to internally handle writing zeroes via WRITESAME16 very fast. Signed-off-by: Peter Lieven <pl@kamp.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2014-04-18doc: grammify "allows to"Michael Tokarev
English language grammar does not allow usage of the word "allows" directly followed by an infinitive, declaring constructs like "something allows to do somestuff" un-grammatical. Often it is possible to just insert "one" between "allows" and "to" to make the construct grammatical, but usually it is better to re-phrase the statement. This patch tries to fix 4 examples of "allows to" usage in qemu doc, but does not address comments in the code with similar constructs. It also adds missing "the" in the same line.
