[PATCH net-next] vhost: switch to use new message format
We use to have message like:
struct vhost_msg {
int type;
union {
struct vhost_iotlb_msg iotlb;
__u8 padding[64];
};
};
Unfortunately, there will be a hole of 32bit in 64bit machine because
of the alignment. This leads a different formats between 32bit API and
64bit API. What's more it will break 32bit program running on 64bit
machine.
So fixing this by introducing a new message type

[COMMON PATCH v3 1/4] inject_virtio_win: match only vendor/device/revision
From: Roman Kagan <rkagan at virtuozzo.com>
Since different hypervisor vendors are allowed to use their own vendor-id
as PCI subsystem-vendor-id for virtio devices, during v2v conversion it
makes sense to only match the vendor/device/revision and not the full device
"path" in the Windows registry. This way the code will remain universal but
will work for different hypervisor

[PATCH v4 1/2] v2v: bootloaders: search grub config for all distributions
From: Pavel Butsykin <pbutsykin@virtuozzo.com>
This patch improves the search of grub config on EFI partition. This
means that the config will be found not only for rhel but also for
many other distributions. Tests were performed on the following
distributions: centos, fedora, ubuntu, suse. In all cases, the config
path was /boot/efi/EFI/*distname*/grub.cfg

[PATCH] v2v: recognize Virtuozzo tools as Parallels tools
Recent updates of Virtuozzo Server 6 (fka Parallels Cloud Server 6) have
"Virtuozzo tools" instead of "Parallels tools" as their display name in
the corresponding Uninstall registry key.
Recognize those, too, and schedule their uninstallation on first boot.
