How to LD_PRELOAD jemalloc to kvm ?

[adoII]

Hi List,

the latency of ceph io is quite high under kvm.

The guys in the ceph mailing list say latency can be improved by preloading jemalloc to kvm binary.

Is there a nice and elegant way to prepend spmething LD_PRELOAD=$LD_PRELOAD:/usr/lib64/libjemalloc.so.1 to the kvm call in proxmox ?

Many Greetings

PVE's version of Qemu is already built (and linked) with jemalloc.
