Re: Console - VNC password is 12 characters long, only 8 permitted

by Francesco Lorenzini

Hi Crhis, I didn't resolve properly, I found that downgrading libvirt was the fastest workaround. Just downgrade libvirt via yum/dnf to to version 7.10. I added the downgrade in an Ansible task, if you are practical: - name: Ensure libvirt-7.10.0 is installed yum: name: libvirt-7.10.0 state: present update_cache: true allow_downgrade: true ignore_errors: true or via cli : yum install libvirt-7.10.0 Post dowgrade we performed a restart of vdsm (or super-vdsm, or both, I don't remember). The downgrade is quite safe, we didn't encounter any problem with existing hosts and new deployed one.

Console - VNC password is 12 characters long, only 8 permitted

by francesco＠shellrent.com

Hi all, I'm using websockify + noVNC for expose the vm console via browser getting the graphicsconsoles ticket via API. Everything works fine for every other host that I have (more than 200), the console works either via oVirt engine and via browser) but just for a single host (CentOS Stream release 8, oVirt 4.4.9) the console works only via engine but when I try the connection via browser I get the following error (vdsm log of the host): ERROR FINISH updateDevice error=unsupported configuration: VNC password is 12 characters long, only 8 permitted Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/vdsm/common/api.py", line 124, in method ret = func(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/API.py", line 372, in updateDevice return self.vm.updateDevice(params) File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 3389, in updateDevice return self._updateGraphicsDevice(params) File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 3365, in _updateGraphicsDevice params['params'] File "/usr/lib/python3.6/site-packages/vdsm/virt/vm.py", line 5169, in _setTicketForGraphicDev self._dom.updateDeviceFlags(xmlutils.tostring(graphics), 0) File "/usr/lib/python3.6/site-packages/vdsm/virt/virdomain.py", line 101, in f ret = attr(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/common/libvirtconnection.py", line 131, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/common/function.py", line 94, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python3.6/site-packages/libvirt.py", line 3244, in updateDeviceFlags raise libvirtError('virDomainUpdateDeviceFlags() failed') libvirt.libvirtError: unsupported configuration: VNC password is 12 characters long, only 8 permitted The error is pretty much self explanatory but, I can't manage to figure out why only on this server and I wonder if I can set the length of the generated vnc password somewhere. Thank you for your time, Francesco

Link multiple self-hosted engines

by ravi k

Hello, We are planning to install self-hosted engines in our production and DR locations which are separated physically. VMware's vcenter has a feature wherein we can link vcenters so we can access both DCs in the same console. Do we have something like that in oVirt as well? I was searching and found this for oVirt 3.5 https://lists.ovirt.org/archives/list/users@ovirt.org/thread/4LDSUM4NRHUO... The suggestion which mentions about using ManageIq seemed interesting. If anyone is managing multiple oVirt environments please share some ideas from experience. Regards, Ravi

about the time of the warning message on the engine web

by Tommy Sway

Why is the alarm information displayed on the ovirt Engine information page inconsistent with the actual time, or even later than the current time? The time of the server where the engine resides and the managed servers have been synchronized to the latest time. Why does a similar problem occur? Thanks.

Re: [External] : Importing KVMs and QCOW

by Abe E

Thanks for the reply. Yes I was able to make it work in the end, for some reason Ovirt didnt recognize the QCOW or Raw files as they were, so instead I took the vmdk my vendor provided me and converted it to qcow and ovirt then recognized it correctly.

Long shot on VM failing to start

by simon＠justconnect.ie

We are moving to an oVirt 4.4.9 environment from a 4.3.4.3 environment and have run into a major issue. The method for migration to the new system is to shutdown a VM on the old system, build a new VM on the new system with the same IP/name etc. This has worked for several VMs so far but the latest new build failed and we had to roll back - i.e. start the old VM. The old VM fails to start with the following message in the VMs libvirt qemu log: libvirtd quit during handshake: Input/output error shutting down, reason=failed Any ideas? Regards Simon...

virt-viewer-x64.msi location

by auricomdyx＠gmail.com

Hello, I'm trying to download viewer for connecting to VMs, the documentation https://www.ovirt.org/documentation/virtual_machine_management_guide/inde... mentions the URL should be https://your-manager-fqdn/ovirt-engine/services/files/spice/virt-viewer-x... However substituting my ovirt-engine hostname for "your-manager-fqdn", I get 404. I even SSH directly into hosted engine VM and was not able to locate virt-viewer-x64.msi on the file system. If I go to https://your-manager-fqdn/ovirt-engine/ landing page. The "Console Client Resources" goes to: https://www.ovirt.org/documentation/admin-guide/virt/console-client-resou... Which is also a 404. Am I supposed to be downloading it from here (weary of unsigned publishers, but looks like the only place where this is located)? https://virt-manager.org/download/ Version is: Version 4.4.10.6-1.el8 Installed on: CentOS Stream 8 (8.5) Install instructions used: https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_eng...

Hi all, I try to install hosted-engine on node : ovirt-node-ng-4.2.3-0.20180518. Every times I get stuck on : [ ERROR ] fatal: [localhost]: FAILED! => {"attempts": 50, "changed": true, "cmd": "virsh -r net-dhcp-leases default | grep -i 00:16:3e:6c:5a:91 | awk '{ print $5 }' | cut -f1 -d'/'", "delta": "0:00:00.108872", "end": "2018-06-01 11:17:34.421769", "rc": 0, "start": "2018-06-01 11:17:34.312897", "stderr": "", "stderr_lines": [], "stdout": "", "stdout_lines": []} I tried with static IP Address and with DHCP but both failed. To be more specific, I installed three nodes, deployed glusterfs with the wizard. I'm in a nested virtualization environment for this lab (Vmware Esxi Hypervisor). My node IP is : 192.168.176.40 / and I want the hosted-engine vm has 192.168.176.43. Thanks, Florent
