[Users] Horrid performance during disk I/O
by Blaster 16 Jan '14

16 Jan '14

This probably more appropriate for the qemu users mailing list, but that list doesn’t get much traffic and most posts go unanswered… As I’ve mentioned in the past, I’m migrating my environment from ESXi to oVirt AIO. Under ESXi I was pretty happy with the disk performance, and noticed very little difference from bare metal to HV. Under oVirt/QEMU/KVM, not so much…. Running hdparm on the disk from the HV and from the guest yields the same number, about 180MB/sec (SATA III disks, 7200RPM). The problem is, during disk activity, and it doesn’t matter if it’s Windows 7 guests or Fedora 20 (both using virtio-scsi) the qemu-system-x86 process starts consuming 100% of the hypervisor CPU. Hypervisor is a Core i7 950 with 24GB of RAM. There’s 2 Fedora 20 guests and 2 Windows 7 guests. Each configured with 4 GB of guaranteed RAM. Load averages can go up over 40 during sustained disk IO. Performance obviously suffers greatly. I have tried all combinations of having the guests on EXT 4, BTRFS and using EXT 4 and BTRFS inside the guests, as well as direct LUN. Doesn’t make any difference. Disk IO sends qemu-system-x86 to high CPU percentages. This can’t be normal, so I’m wondering what I’ve done wrong. Is there some magic setting I’m missing?

[Users] Management server
by Koen Vanoppen 16 Jan '14

16 Jan '14

Dear All, Our setup at work now is: 1 management server and 7 hyper visors. All the systems have centos 6.4 on it. Now my question is: Because of the fact that all the systems have centos on it, we can't use the reports portal and the dwh-portal. Would it be possible to add a second management server to our already existing setup (fedora 19), without !*breaking*! our existing setup, so this one can provide us with the reports and dwh-portal and can also serve as a "Back-Up" management server. If so, how do we handle this? Kind regards, Koen

[Users] ovirt-engine-reports rpm for CentOS and oVirt 3.3
by Nicolas Ecarnot 16 Jan '14

16 Jan '14

Good morning or whenever, I read what RPM I have to install here http://www.ovirt.org/Ovirt_Reports but I can not find any RPM for CentOS 6. I strongly searched around the web and in the different repo folders, as well as in the mailing list msgs, and it seems the production of RPM for CentOS has been disabled for whatever reason. Is there a private recipe to create them or get them an unofficial way (reports, dwh, jasperreports...) Thank you. -- Nicolas Ecarnot

[Users] oVirt node - network config not persisted
by Federico Alberto Sayd 16 Jan '14

16 Jan '14

Hello: I have been testing some hosts with ovirt-node (3.0.1-1.0.2.el6) and when I reboot the node the network config is not persisted. I have seen that this was commented in this list, some time ago. Was this fixed in 3.0.3-1 release? There is a 3.0.3-1.1 image in http://resources.ovirt.org/releases/3.3/iso/, but is only Fedora Core. No el6/Centos image? Thank you Federico

Please also update the target to 3.4.1 or any next release for bugs that won't be in 3.4.0: it will ease gathering the blocking bugs for next releases. For those who want to help testing the bugs, I suggest to add yourself as QA contact for the bug. -- Sandro Bonazzola Better technology. Faster innovation. Powered by community collaboration.
