It happens also with qemu-kvm 2.2.0 on another VM where also PostgreSQL 
is running:
(gdb) bt
#0  0x00007fff9a1feff4 in gettimeofday ()
#1  0x00000000006d425e in GetCurrentTimestamp () at timestamp.c:1274

What we know:
OK : F20: 3.17.6-200.fc20.x86_64 on guest/host, 
qemu-kvm-1.6.2-10.fc20.x86_64 on host
NOK: F21: 3.17.7-300.fc21.x86_64 on guest/host, 
qemu-kvm-2.1.2-7.fc21.x86_64 on host
NOK: F21: 3.17.8-300.fc21.x86_64 on guest/host, 
qemu-kvm-2.2.0-1.fc21.x86_64 on host

No one less can reproduce or has similar problems?
Any further ideas?

BTW: I'm running ntp in the following manner: internet <=> ntp server in 
VM <=> ntp client on KVM host (firewall runs in KVM)

Ciao,
