нет Майк - это таки не dns. Посидел с strace - оно тормозит на

futex(0x7db354, FUTEX_WAIT_PRIVATE, 4, NULL) = -1 EAGAIN (Resource 
temporarily unavailable)
futex(0x7db354, FUTEX_WAIT_PRIVATE, 5, NULL) = 0
futex(0x7db328, FUTEX_WAIT_PRIVATE, 2, NULL) = 0
futex(0x7db328, FUTEX_WAKE_PRIVATE, 1)  = 0
futex(0x7db354, FUTEX_WAIT_PRIVATE, 9, NULL) = 0
futex(0x7db328, FUTEX_WAIT_PRIVATE, 2, NULL) = 0
futex(0x7db328, FUTEX_WAKE_PRIVATE, 1)  = 0
futex(0x7db354, FUTEX_WAIT_PRIVATE, 19, NULL

(и таких кусков с разными пидами довольно много)

тормозит по 6-10 секунд примерно. и стабильно после почти каждого 
рестарта libvirtd
