%description
Suite of daemons that are needed when Linux guest
is running on Windows Host with HyperV.


%package -n hypervkvpd
Summary: HyperV key value pair (KVP) daemon
Group:   System Environment/Daemons
Requires: %{name}-license = %{version}-%{release}
BuildRequires: systemd, kernel-devel
Requires(post):   systemd
Requires(preun):  systemd
Requires(postun): systemd

%description -n hypervkvpd
Hypervkvpd is an implementation of HyperV key value pair (KVP) 
functionality for Linux. The daemon first registers with the
kernel driver. After this is done it collects information 
requested by Windows Host about the Linux Guest. It also supports
IP injection functionality on the Guest.


%package -n hypervvssd
Summary: HyperV VSS daemon
Group:   System Environment/Daemons
Requires: %{name}-license = %{version}-%{release}
BuildRequires: systemd, kernel-devel
Requires(post):   systemd
Requires(preun):  systemd
Requires(postun): systemd

%description -n hypervvssd
Hypervvssd is an implementation of HyperV VSS functionality
for Linux. The daemon is used for host initiated guest snapshot
on HyperV hypervisor. The daemon first registers with the
kernel driver. After this is done it waits for instructions 
from Windows Host if to "freeze" or "thaw" the filesystem
on the Linux Guest.
