Unable to remove system roles from Everyone group
by miguel.garcia＠toshibagcs.com 02 May '20

02 May '20

I opened Everyone group and added system role UserRole and realized now that everybody can see all VMS which is not good. I tried to remove the role from the group but got the error "Error while executing action: It's not allowed to remove system permissions assigned to built-in Everyone group" Looking into Ovirt forums I see that this change should be made through the engine database but I was not able to reach that part. Can someone help me out how to remove the system role from Everyone group? or at least reset the group?

Can we agree on adding reference to version in help request email?
by Sandro Bonazzola 30 Apr '20

30 Apr '20

Hi, I was looking in the past 2 weeks email landing on this mailing list and a common thing I notice is that it's hard to understand which version of the involved software they're referring too. Can we agree on adding at the top of the message a couple of line like output of yum -q list installed centos-release ovirt-release\* ovirt-engine redhat-release vdsm glusterfs centos-release.x86_64 7-7.1908.0.el7.centos glusterfs.x86_64 6.8-1.el7 ovirt-engine.noarch 4.3.9.4-1.el7 ovirt-release43.noarch 4.3.9-1.el7 It will help understanding if the help request is something that may be already known, a regression, and so on. -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://www.redhat.com/>* <https://www.redhat.com/en/summit?sc_cid=7013a000002D2QxAAK>* *Red Hat respects your work life balance.

ovrt node ng 4.4 different fs layout and error if changed
by Gianluca Cecchi 29 Apr '20

29 Apr '20

Hello, In CentOS 7 default filesystem in anaconda was xfs, but in ovirt node ng 4.3.9 (based on CentOS 7) the default layout was set to ext4. In CentOS 8 again the default is xfs and I see that ovirt node ng 4.4 beta4 (based on CentOS 8.1) has now xfs for all filesystems, excluded /boot that is set to ext4. In general I have a preference for ext4. I notice that while in 4.3.9 I could somehow customize partition layout, even if not recommended, in 4.4 I always get error if I don't accept automatic partitioning. What I sometimes do: - select disk and custom layout - click done and the storage page appears - I click the button to create automatically and I get the automatic partitioning layout - and here I can change fs type and update settings button and/or change size of some filesystems (eg for /var/log if using Gluster) Even if I only set all filesystems automatically generated by installer to ext4, without changing any size, in the final stage of installation I get this error and installation aborts: " There was an error running the kickstart script at line 5. This is a fatal error and installation will be aborted. The details of this error are: 2020-04-19 10:37:50,451 [INFO] (MainThread) Trying to create a manageable base from '/' 2020-04-19 10:37:50,811 [ERROR] (MainThread) LVM Thin Provisioning partitioning scheme is required.

Tried different times with same results. Is it expected? In this case instead of specifying "recommended" it should be written sort of "mandatory"... Gianluca

Problem with multiple IP addresses and AWX
by Bernhard Dick 29 Apr '20

29 Apr '20

Hi, I've started to use awx shortly and I'd like to have an inventory based on their RHEV/oVirt-Plugin. Basically that works fine, however on machines that have multiple network interfaces or internal nets (like Docker) the first address in the IP list of the vm (which is used as ansible_host by AWX) is not an address that is reachable from the machine's outside and so those host entries are failing in my jobs. I found an issue at AWX, being like we won't fix first: https://github.com/ansible/awx/issues/1191 It also seems that there where issues related to this on oVirt: First this with a request for setting a primary IP: https://bugzilla.redhat.com/show_bug.cgi?id=1437145 And this one mentioning a way to ignore interfaces on ovirt-guest-agent, however it does no longer work due to the use of qemu-guest-agent: https://bugzilla.redhat.com/show_bug.cgi?id=1437145 Do you have any ideas how to circumvent this or is there some improvement alread in planning? Best regards Bernhard

Can't ping gluster interfaces for HCI setup
by Shareef Jalloq 29 Apr '20

29 Apr '20

Hi, I'm in the process of trying to set up an HCI 3 node cluster in my homelab to better understand the Gluster setup and have failed at the first hurdle. I've set up the node interfaces on the built in NIC and am using a PCI NIC for the Gluster traffic - at the moment this is 1Gb until I can upgrade - and I've assigned a static IP to both interfaces and also have both entries in my DNS. From any of the three nodes, I can ping the gateway, the other nodes, any external IP but I can't ping any of the Gluster NICs. What have I forgotten to do? Here's the relevant output of 'ip addr show'. em1 is the motherboard NIC and p1p1 is port 1 of an Intel NIC. The /etc/sysconfig/network-scripts/ifcfg-<if> scripts are identical aside from IPADDR, NAME, DEVICE and UUID fields. Thanks, Shareef. [root@ovirt-node-00 ~]# ip addr show 2: p1p1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether a0:36:9f:1f:f9:78 brd ff:ff:ff:ff:ff:ff inet 10.0.0.34/24 brd 10.0.0.255 scope global noprefixroute p1p1 valid_lft forever preferred_lft forever inet6 fd4d:e9e3:6f5:1:a236:9fff:fe1f:f978/64 scope global mngtmpaddr dynamic valid_lft 7054sec preferred_lft 7054sec inet6 fe80::a236:9fff:fe1f:f978/64 scope link valid_lft forever preferred_lft forever 4: em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 98:90:96:a1:16:ad brd ff:ff:ff:ff:ff:ff inet 10.0.0.31/24 brd 10.0.0.255 scope global noprefixroute em1 valid_lft forever preferred_lft forever inet6 fd4d:e9e3:6f5:1:9a90:96ff:fea1:16ad/64 scope global mngtmpaddr dynamic valid_lft 7054sec preferred_lft 7054sec inet6 fe80::9a90:96ff:fea1:16ad/64 scope link valid_lft forever preferred_lft forever
