--- Begin Message ---Source: linux Version: 3.16~rc5-1~exp1 Severity: important Hi Ben I choosed important as severity, as it causes a regression from wheezy->jessie for installation of kvm guests with kernel in the d-i, but actually it might be overrated, please downgrade if you don't agree. Background: For tests I often use the following instruction to quickly create vms (either preseeded or without preseed): http://honk.sigxcpu.org/con/Preseeding_Debian_virtual_machines_with_virt_install.html also having the console output to ttyS0, the kernel arguments are auto keymap=us hostname=foo netcfg/get_ipaddress=192.168.122.123 suite=unstable -- console=ttyS0,115200n8 in the example case. When altough using the current d-i with a 3.16.2-2 the kernel I don't see anymore neither the kernel boot messages nor the started d-i anymore when virt-install connects to the virtual serial console for the guest and cannot proceed with installation in d-i. I was able to track this down to a change between 3.15.5-1~exp1 and 3.16~rc5-1~exp1 but unfortuantely don't have a specific commit. To reproduce I attach the small 'reproducer.sh' shellscript which fetches the d-i linux and initrd.gz from -location=${HOME}/virt/installer-amd64/ (see below) and also sets auto keymap=us hostname=foo netcfg/get_ipaddress=192.168.122.123 suite=unstable -- console=ttyS0,115200n8 as kernel arguments. It is ----cut---------cut---------cut---------cut---------cut---------cut----- #!/bin/bash virt-install --connect=qemu:///system \ --graphics none \ --location=${HOME}/virt/installer-amd64/ \ --extra-args="auto keymap=us hostname=foo netcfg/get_ipaddress=192.168.122.123 suite=unstable -- console=ttyS0,115200n8" \ --name foo \ --ram 1024 \ --disk=pool=default,size=5,format=qcow2,bus=virtio,cache=writeback ----cut---------cut---------cut---------cut---------cut---------cut----- ${HOME}/virt/installer-amd64 would look as follows: ----cut---------cut---------cut---------cut---------cut---------cut----- $ ls -1R installer-amd64 installer-amd64: current installer-amd64/current: images installer-amd64/current/images: MANIFEST netboot installer-amd64/current/images/netboot: debian-installer installer-amd64/current/images/netboot/debian-installer: amd64 installer-amd64/current/images/netboot/debian-installer/amd64: initrd.gz linux ----cut---------cut---------cut---------cut---------cut---------cut----- and the MANIFEST file only need to contain ----cut---------cut---------cut---------cut---------cut---------cut----- netboot/debian-installer -- PXE boot directory for tftp server ----cut---------cut---------cut---------cut---------cut---------cut----- So basically stripped down content as you would find in http://ftp.ch.debian.org/debian/dists/unstable/main/installer-amd64/ If I use initrd.gz and linux from 20140802 installation works fine if I use the ones from current (20141002) the above behavious is observed, no installer ist seen. I then afterwards replaced the linux image to find closer version were the problem appear, and looks like 3.15.5-1~exp1 is good, 3.16~rc5-1~exp1 is bad. Quite some changes with merge in commit 49eb7b0750d9483c74e9c14ae6ea1e9d62481c3c The mentioned setup is running on Debian stable with libvirt/0.9.12.3-1+deb7u1, qemu-kvm/1.1.2+dfsg-6+deb7u4.

So even though the change was introduced between v3.15 and 3.16 it is not something that should be reverted clearly. Closing the bug, sorry for the noise. Regards, Salvatore
