It was after a host update. I did not change or update the quest.

I do not know how to do what you ask. I looked everywhere on launchpad
and could not find older .debs.

However, my previous ones were still in my cash:

doug at s15:~$ locate .deb | grep qemu
/var/cache/apt/archives/qemu-keymaps_2.0~git-20140228.d844a7b-0ubuntu1_all.d
eb
/var/cache/apt/archives/qemu-kvm_2.0~git-20140228.d844a7b-0ubuntu1_amd64.deb
/var/cache/apt/archives/qemu-system-common_2.0~git-20140228.d844a7b-0ubuntu1
_amd64.deb
/var/cache/apt/archives/qemu-system-x86_2.0~git-20140228.d844a7b-0ubuntu1_am
d64.deb
/var/cache/apt/archives/qemu-utils_2.0~git-20140228.d844a7b-0ubuntu1_amd64.d
eb

So I installed them. So I went from this (the formatting is going to mess up
when I send):

doug at s15:~$ dpkg -l | grep qemu

To this (the formatting is going to mess up when I send):

doug at s15:~$ dpkg -l | grep qemu

And now everything is working fine (oh, I see I forgot to downgrade
qemu-keymaps...).

I do not think so, since that part did not change.

Note sure what you mean by -vga. I use vmvga and only communicate with my
VMs via VNC (well, I use always install sshd on them as a backup way to talk
to it). The Cirrus driver has never ever worked for me, and as far as I
could determine from my readings, the older bug reports related to vmvga had
been fixed. I have been using it for months. This is the command I used to
create the vm:

sudo virt-install -n desk_tt -r 8192 --disk
path=/home/doug/img/desk_tt.img,bus=virtio,size=50 -c
trusty-desktop-20140302-amd64.iso --network bridge=br0,model=virtio
--video=vmvga --graphics vnc,listen=0.0.0.0 --noautoconsole -v --vcpus=4

However, and typically I use virsh edit afterwards and increase the vram to
16384, because by my math the default 9216 isn't enough. (I do not know how
to set it during install).
