Before you can resize filesystem, you have to resize partition.
If it is only 2 partitions on /dev/vda, you can use one of two ways:
1. Resize partition from host system (I think it is not the best idea for root
Run fdisk /dev/vg/lv_guest1root, delete second partition and create new one
which starts from the same place but takes all available space, after it you
can boot guest (in single mode) and run resize2fs.
2. Boot VM from any 3-party (LiveCD or any) with access to virtual disk, and
do the same: in fdisk delete existing partition, create new one and run
resize2fs on it. Or just use parted to do it in one command.
With best regards
