I stumbled over "updates available" in dashboard, but when I tried to apply them
"The following packages have been kept back: libvirt-clients libvirt-daemon libvirt-daemon-config-network libvirt-daemon-config-nwfilter libvirt-daemon-driver-qemu libvirt-daemon-system libvirt-daemon-system-systemd libvirt0 qemu-system-arm qemu-system-common qemu-system-data qemu-system-mips qemu-system-ppc qemu-system-x86 qemu-utils
0 upgraded, 0 newly installed, 0 to remove and 15 not upgraded."
was reported
I assume these are packages installed via kvm plugin but might be wrong.
To find the reason I was manually running "sudo apt-get install libvirt-clients".
This command asked:
"

What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.
*** qemu.conf (Y/I/N/O/D/Z) [default=N] ?
"
the relevant differences are from my view:
