Hello Serge, I am sorry for the slow response on this. I had a chance to test the packages, and it appears that they have been broken by a change to another package: qemu-system-x86 deps on ipxe-qemu, which appears to have been superceded by ipxe.
The packages are uninstallable in proposed. root@wilk-aio3:~# apt-cache policy qemu-system-x86 qemu-system-x86: Installed: (none) Candidate: 1.5.0+dfsg-3ubuntu5.1 Version table: 1.5.0+dfsg-3ubuntu5.1 0 700 http://archive.ubuntu.com/ubuntu/ saucy-proposed/main amd64 Packages 1.5.0+dfsg-3ubuntu5 0 100 /var/lib/dpkg/status root@wilk-aio3:~# apt-get install qemu-system-x86 Reading package lists...
