[Ovirt 4.0.6] Suggestion required for Network Throughput options
by TranceWorldLogic . 04 Jul '17

04 Jul '17

Hi, To increase network throughput we have changed txqueuelen of network device and bridge manually. And observed improved throughput. But in ovirt I not see any option to increase txqueuelen. Can someone suggest me what will be the right way to increase throughput ? Note: I am trying to increase throughput for ipsec packets. Thanks, ~Rohit

by yayo (j) 03 Jul '17

03 Jul '17

Hi at all, we have a 3 node cluster with this configuration: ovirtzz 4.1 with 3 node hyperconverged with gluster. 2 node are "full replicated" and 1 node is the arbiter. Now we have a new server to add to cluster then we want to add this new server and remove the arbiter (or, make this new server a "full replicated" gluster with arbiter role? I don't know) Can you please help me to know what is the right way to do this? Or, Can you give me any doc or link that explain the steps to do this? Thank you in advance!

HostedEngine VM not visible, but running
by cmc 30 Jun '17

30 Jun '17

Hi, I've migrated from a bare-metal engine to a hosted engine. There were no errors during the install, however, the hosted engine did not get started. I tried running: hosted-engine --status on the host I deployed it on, and it returns nothing (exit code is 1 however). I could not ping it either. So I tried starting it via 'hosted-engine --vm-start' and it returned: Virtual machine does not exist But it then became available. I logged into it successfully. It is not in the list of VMs however. Any ideas why the hosted-engine commands fail, and why it is not in the list of virtual machines? Thanks for any help, Cam

vm shutdown long delay is a problem for users of pools
by Paul 30 Jun '17

30 Jun '17

This is a multipart message in MIME format. ------=_NextPart_000_0079_01D2EB83.89CE5690 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Hi, Shutting down VM's in the portal with the red downfacing arrow takes quite some time (about 90 seconds). I read this is mainly due to a 60 second delay in the ovirt-guest-agent. I got used to right-click and use "power off" instead of "shutdown", which is fine. My users make use of VM in a VM-pool. They get assigned a VM and after console disconnect the VM shuts down (default recommended behavior). My issue is that the users stays assigned to this VM for the full 90 seconds and cannot do "power off". Suppose he disconnected by accident, he has to wait 90 seconds until he is assigned to the pool again until he can connect to another VM. My questions are: - Is it possible to decrease the time delay of a VM shutdown? 90 seconds is quite a lot, 10 seconds should be enough - Is it possible for normal users to use "power off"? - Is it possible to "unallocate" the user from a VM if it is powering down? So he can allocate another VM Kind regards, Paul ------=_NextPart_000_0079_01D2EB83.89CE5690 Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable <html xmlns:v=3D"urn:schemas-microsoft-com:vml" = xmlns:o=3D"urn:schemas-microsoft-com:office:office" = xmlns:w=3D"urn:schemas-microsoft-com:office:word" = xmlns:m=3D"http://schemas.microsoft.com/office/2004/12/omml" = xmlns=3D"http://www.w3.org/TR/REC-html40"><head><meta = http-equiv=3DContent-Type content=3D"text/html; = charset=3Dus-ascii"><meta name=3DGenerator content=3D"Microsoft Word 15 = (filtered medium)"><style></style></head><body lang=3DNL = link=3D"#0563C1" vlink=3D"#954F72"><div class=3DWordSection1>Hi,<o:p></o:p>Shutting = down VM’s in the portal with the red downfacing arrow takes quite = some time (about 90 seconds).

Unable to rename disks via REST API
by Bruno Rodriguez 30 Jun '17

30 Jun '17

Hello everyone, I'm having some problems about renaming some disks (setting a different alias, name or description) for VMs disks created from a template. When I get this URL https://ovirt-manager/ovirt-engine/api/disks/0123 I can see are the methods sparsify, export, move and copy. I tried to POST the following XML to the previous URL with no result (as expected, it won't work) <disk> <alias>my_machine_Disk1</alias> </disk> I'm quite sure I'm thinking about it in a wrong way (as usual). Any help would be welcome... Thank you in advance -- Bruno Rodríguez Rodríguez *Port d'Informació Científica (PIC)*
