grub-install fails on virtio disks

[Stefan Bader]

Wily desktop iso 64bit: 2015-10-13

Steps to reproduce:
1. Start installation from GUI selection "Install Ubuntu" on virtio (vda) disk in a KVM VM
2. Use guided partitioning to erase and install on one disk (other options that are not strictly default: use German keyboard layout and Berlin as location for timezone).

The installation proceeds normally up to the point where the boot loader is supposed to be installed. There the install fails because it tries to install into /dev/vda5 (which got assigned swap). The dialogue that appears allows to select /dev/vda instead, but pressing "OK" has no effect (it also does seem to have no effect when selecting to continue without boot loader).
When I switch to a VT at this time, the install target is not mounted (that might be normal with ubiquity).

Maybe important, that VM guest had 3 virtio disks defined (vda, vdb, and vdc).

Cannot reproduce this anymore.

Just happened again on a Xen HVM guest (only one disk), at least I got a syslog this time.
