cannot install windows(Failed to run vncproxy)

[tiannip]

Hi all,
I install pve on Gen8 (E3-1260Lv1, HHD,10gb ram(2+8)).
On pve, I have created vm use ubuntu as os. All ubuntu vm are runing correctly.
But I cannot install windows on new vm. It alway show the errors as "TASK ERROR: Failed to run vncproxy." when I install os.
Sometime, it can installed windows correctly, but the vm shutdown with out any alarm. Then vm even can not start, and only the info: TASK ERROR: Failed to run vncproxy
I search google and this forum , but cannot get the same problem. So how should I do?

hi,

it looks like you're running out of memory, and the kvm process is getting killed as a result (which causes vncproxy to not connect, because there's nothing to connect to). how much RAM did you assign to this VM?
