Error saat restore backup secara manual

Bebarapa waktu lalu saya mendapatkan laporan dari client yang mengalami error saat restore backup secara manual, beliau tidak dapat me-restore backup dari image VM ke server node proxmox yang baru.
berikut ini adalah errornya

restore vma archive: vma extract -v -r /var/tmp/vzdumptmp13709.fifo /var/lib/vz/dump/vzdump-qemu-100-2015_02_04-10_27_01.vma /var/tmp/vzdumptmp13709

TASK ERROR: command 'vma extract -v -r /var/tmp/vzdumptmp13709.fifo /var/lib/vz/dump/vzdump-qemu-100-2015_02_04-10_27_01.vma /var/tmp/vzdumptmp13709' failed: command '/usr/bin/qemu-img create -o 'preallocation=metadata' -f qcow2 /var/lib/vz/images/111/vm-111-disk-1.qcow2 367001600K' failed: got timeout

client saya menggunakan Proxmox Versi 3.2-1/1933730b. setelah saya telusuri lebih dalam, error tersebut memang bugs dari proxmox itu sendiri
silahkan cek versi qemu-server anda dengan menggunakan perintah dibawah ini

Error saat restore backup secara manual

root@proxmox-arielfx~# pveversion -v | grep qemu-server
qemu-server: 3.1-15

jika qemu-server anda sama seperti diatas, silahkan upgrade qemu-server anda secara manual dengan cara

root@proxmox-arielfx~# wget http://mirror.webnx.com/proxmox/dists/wheezy/pve-no-subscription/binary-amd64/qemu-server_3.1-16_amd64.deb
root@proxmox-arielfx~# dpkg -i qemu-server_3.1-15_amd64.deb

setelah upgrade qemu-server selesai, silahkan coba kembali untuk restore backup anda. hasilnya nanti akan seperti dibawah ini
