Re: [ovirt-users] Allocating only "x" amount of physical memory to hypervisor node

2016-12-23 Thread Martin Sivak
Hi, I believe we do not support this, but there is something similar in the VDSM configuration (/etc/vdsm/vdsm.conf). There are two options: host_mem_reserve and extra_mem_reserve that allow you to reserve memory for the OS and your application. You should be aware of features like fencing

[ovirt-users] NAS for oVirt

Hi all, I am thinking to setup an environment with oVirt and centralized storage using a NAS that supports NFS and iSCSI. The setup will be used to host approx 20 VMs. The VMs will be running critical services and not for testing. I have seen several from QNAP, iXsystems (freenas mini), ...

[ovirt-users] Why difference between upgrade paths 3.6 to 4.0.x between RHEV and oVirt?

2016-12-23 Thread Gianluca Cecchi
Hello, in June 2016 oVirt 4.0.0 GA was released and I in-place upgraded from an existing 3.6.5 to it. In 4.0.0 release notes it was described as the method to use. I see that it still remains the same for 4.0.5: http://www.ovirt.org/release/4.0.5/ and also for upcoming 4.0.6 (RC5 at least) there

Hello Alex, Specs you provided are a little bit vague. You don’t specify storage space. Our main storage here is a SAN Compellent, but we do have also Synology and we are quite happy with it You can start searching this or comparable product https://www.synology.com/en-global/products/RS2416+

Hi Mikhail, Thank you for your suggestion. Have you had any performance issues with freenas? It has been mentioned on some blogs that freenas might have performance issues. Not sure why. A clean Centos with NFS sounds ok also. What do you do if you need snapshots of data? Lvm snapshots? Alex
