[Qemu-devel] [PATCH v2] vmdk: Optimize cluster allocation

On mounted NFS filesystem, ftruncate is much much slower than doing a zero write. Changing this significantly speeds up cluster allocation. Comparing by converting a cirros image (296M) to VMDK on an NFS mount point, over 1Gbe LAN: $ time qemu-img convert cirros-0.3.1.img /mnt/a.raw -O vmdk
