With the default 2G it happens 1 in every 4-6 times. I change it to 3G and I've had it happen once in the last 25 installations (however I had added src to the installation it failed on with 3G). I have had the same error occur with RC2 and RC3 About my environment: FreeBSD virtual device on Ubuntu/KVM 2 disks, 30 gig each. Each iscsi disk is on a different virtual instance of FreeBSD running istgt >How-To-Repeat: freebsd cd rebuilt as following (I'm building on the ubuntu device but it shouldn't matter where it's built): mount -o loop FreeBSD-10.0-RC3-amd64-disc1.iso /mnt mkdir /tmp/new-freebsd cp -Rfp /mnt/* /tmp/new-freebsd/ sed -i '/^ttyu0/s/off/on/;/^ttyu0/s/dialup/vt100/' /tmp/new-freebsd/etc/ttys echo "console=\"comconsole\"" >> /tmp/new-freebsd/boot/loader.conf echo "virtio_load=\"YES\"" >> /tmp/new-freebsd/boot/loader.conf echo "virtio_pci_load=\"YES\"" >> /tmp/new-freebsd/boot/loader.conf echo "beastie_disable=\"YES\"" >> /tmp/new-freebsd/boot/loader.conf echo "/dev/cd0 / cd9660 ro 0 0" > /tmp/new-freebsd/etc/fstab mkisofs -v -b boot/cdboot -no-emul-boot -r -J -V "FreeBSD 9.2" -o /var/lib/libvirt/iso/FreeBSD-10.0-RC3-new.iso /tmp/new-freebsd/ now start an install with the command: virt-install -n mail0 -r 2048 --vcpus=2 --os-variant=freebsd8 --accelerate -v --disk path=/dev/mapper/mail0-f0,bus=virtio,size=30 --disk path=/dev/mapper/mail0-f1,bus=virtio,size=30 -w bridge:br1,model=virtio -c /var/lib/libvirt/iso/FreeBSD-10-rc3-new.iso --connect=qemu:///system *Note the two disk names in /dev/mapper.
