When converting from hx to texi format, hxtool (or to be more precise sh which interprets hxtool) used standard shell expansion of wildcards while writing lines to the output. Thus, something like "Password: ********" looked very different in the generated documentation. The patch disables this unwanted wildcard expansion. Signed-off-by: Stefan Weil <weil@mail.berlios.de>

We want to do (at least) two things to the virtio-balloon device: suppress it, and control its PCI address. Option -no-virtio-balloon lets us do only the former. To get the latter, replace -no-virtio-balloon with -balloon none disable balloon device -balloon virtio[,addr=str] enable virtio balloon device (default) Syntax suggested by Anthony Liguori.

Valgrind was so kind to remark that no one bothers to release keycodes after use and that something is fishy about cleaning up the requested keyboard descriptor.

This patch aligns the KVM-related layout and encoding of the CPU state to be saved to disk or migrated with qemu-kvm. The major differences are reordering of fields and a compressed interrupt_bitmap into a single number as there can be no more than one pending IRQ at a time.

At this point, this refactoring looks like overkill. But we will need it for CPU hotplugging, and qemu-kvm already carries it. Merging it early would help qemu-kvm when rebasing against upstream. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Refactor the ACL monitor interface to make full use of the monitor command dispatcher. This also gives proper help formatting and command completion.

During startup and after reset we have to synchronize user space to the in-kernel KVM state. Namely, we need to transfer the VCPU registers when they change due to VCPU as well as APIC reset. This patch refactors the required hooks so that kvm_init_vcpu registers its own per-VCPU reset handler and adds a cpu_synchronize_state to the APIC reset. That way we no longer depend on the new reset order (and can drop this disliked interface again) and we can even drop a KVM hook in main().

The really time consuming part of snapshotting is to adjust the reference count of all clusters. Currently after each adjusted cluster the refcount block is written to disk. Don't write each single byte immediately to disk but cache all writes to the refcount block and write them out once we're done with the block.

When using O_DIRECT, qcow2 snapshots didn't work any more for me. In the process of creating the snapshot, qcow2 tries to pwrite some new information (e.g. new L1 table) which will often end up being after the old end of the image file. Now pwrite tries to align things and reads the old contents of the file, read returns 0 because there is nothing to read after the end of file and pwrite is stuck in an endless loop. This patch allows to pread beyond the end of an image file. Whenever the given offset is after the end of the image file, the read succeeds and fills the buffer with zeros.
