Hello,
I try to save a KVM domain which has its hard disk on a LVM volume. I can execute the command to save the domain but restore fails
# virsh list Id Name State ---------------------------------- 3 kvm-linux03 running 4 kvm-linux01 running
# virsh save kvm-linux01 ./kvm-linux01.ram Domain kvm-linux01 saved to ./kvm-linux01.ram

You don't mention which version of KVM or libvirt being used, or which distro. If its Fedora then plesae file a bug against libvirt or KVM. There's one possible issue in KVM that could be causing it depending on which version you're using.
I tried to save and restore this domain using kvm directly
# /usr/bin/qemu-kvm -m 1024 -boot c -drive file=/dev/virtual/kvm_linux01,if=ide,index=0,boot=on -net nic,macaddr=00:16:3e:00:01:02,vlan=0 -net tap,fd=24,script=,vlan=0,ifname=vnet3 (qemu) savevm kvm-linux01.ram Device id0-hd0 does not support VM state snapshots
Libvirt doesn't use savevm - it uses the migration protocol support instead.
