Re: [ovirt-users] [FC22] testing oVirt 3.6.2 : Hot plug memory not working

Try: 1. Look for memory that appears offline. Run this command to check the state of the memory: grep line /sys/devices/system/memory/*/state 2. When memory appears offline, run this command to set it to online: echo online >/sys/devices/system/memory/memory[number]/state Yaniv Dary Technical Product Manager Red Hat Israel Ltd. 34 Jerusalem Road Building A, 4th floor Ra'anana, Israel 4350109 Tel : +972 (9) 7692306 8272306 Email: ydary(a)redhat.com IRC : ydary On Mon, Feb 1, 2016 at 3:46 PM, wodel youchi <wodel.youchi(a)gmail.com&gt; wrote: > What do mean? > I have to use RHEL7?
