[Qemu-devel] [Bug 1101210] Re: qemu 1.4.2: usb keyboard not fully working

With a freshly compiled version of qemu 4.0.50 on Widows 10 (host) I am using 3 different Belgian keyboards and I have the same behaviour - 2 USB keyboards (Logitech and HP) and - the keyboard of my laptop (HP) 3 characters on the same key cannot be used (the key seams to be dead): < (less than),

[Qemu-devel] [PATCH v0 1/3] qcow2: introduce compression type feature

The patch adds some preparation parts for incompatible compression type feature to QCOW2 header that indicates that *all* compressed clusters must be (de)compressed using a certain compression type. It is implied that the compression type is set on the image creation and can be changed only later

[Qemu-devel] [PATCH v0 3/3] qcow2: add zstd cluster compression

zstd significantly reduces cluster compression time. It provides better compression performance maintaining the same level of compression ratio in comparison with zlib, which, by the moment, has been the only compression method available. The performance test results: Test compresses and decompres

[Qemu-devel] [PATCH v0 0/3] add zstd cluster compression

The goal of the patch-set is to enable qcow2 to use zstd compression for clusters. ZSTD provides better (de)compression performance than currently used ZLIB. Using it will improve perforamnce (reduce compression time) when the compressed clusters is used, e.g backup scenarios. Also, the patch-set

[Qemu-devel] [PATCH v0 2/3] qcow2: add compression type processing

With the patch, qcow2 is able to process image compression type defined in the image header and choose the corresponding method for clusters compressing. Also, it rework the cluster compression code for adding more compression types. Signed-off-by: Denis Plotnikov --- block/qcow2.c | 103 ++

[Qemu-devel] [Bug 1829242] Re: qemu on windows host exits after savevm command

I think you'll have to break out a debugger on it to see why it's exiting; if you can break on any exit paths and get a backtrace we can have some more guesswork. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.
