Re: [ANN] oVirt 4.3.4 First Release Candidate is now available

Hi Sandro, Thanks for the update. I have just upgraded to RC1 (using gluster v6 here) and the issue I detected in 4.3.3.7 - where gluster Storage domain fails creation - is still present. Can you check if the 'dd' command executed during creation has been recently modified ? I've received update from Darrell (also gluster v6) , but haven't received an update from anyone who is using gluster v5 -> thus I haven't opened a bug yet.

Virtual office, how?
by andres.b.dev＠gmail.com 20 May '19

20 May '19

I'm trying to be able to create different virtual LANs, where, for example, I have 2 groups of pcs A and B belongs to network N1 C and D belongs to network N2 N1 and N2 with his own public IP. For example A: Local ip: 192.168.122.100 B: Local ip: 192.168.122.101 C: Local ip: 192.168.122.102 D: Local ip: 192.168.122.103 Where A and B has the same public ip, and C and D has the same public ip. Now, I want that A can ssh on B, but not on C or D. The same goes for C, where C can access to D via ssh but not to A or B I'm not sure if OVS solve this problem or not, or if this is not possible. Is this possible? How?

Every now and then Backup question
by Markus Schaufler 20 May '19

20 May '19

Hi, looking for a backup solution compareable to vmware/veeam - ie. features like agent-less, incremental, lan-free backups with dedup and single item restore. As I understand the main construction site for all commercial backup solutions available for kvm/rhev was the underlying qemu with its CBT implementation. The main functions should now be implemented as there are solutions like vprotect which state that they support incremental backups for rhev. But as I read at https://www.openvirtualization.pro/agent-less-backup-strategies-for-ovirt-r… there might still be some drawbacks. Are there ressources or a roadmap covering the state of the backup/recovery process, ie. what is possible now and whats in progress? I'm sure a big showstopper for open source virtualization projects are is uncertainty about backup/recovery and especially disaster recovery processes. Follow up questions to the users with bigger environments: Whats your current backup and DR strategy? Does anybody have experience with commercially availbe backup solutions like Bacula, SEP, Commvault, etc.?

newbie questions about installation using synology NAS
by bmillett＠gmail.com 20 May '19

20 May '19

I'm starting fairly fresh. Ovirt engine 4.3.3.7 on a host 2 nodes installed with ovirt-release-host-node-4.3.3.1 synology DS418 with 5 TB disks I've configured the master engine and am ready to add the nodes. My questions have to do with the order or steps . Do I need to mount /volume1/data/images/rhev from the DS418 on each of the nodes before I add them or do I just add the nodes, then define a domain using the NFS mounts from the DS418? Thanks.

Define the nodes and when you create your NFS storage domain - it will be automatically mounted on all hosts in the DC.

I would recommend you to postpone your upgrade if you use gluster (without the API) , as creation of virtual disks via UI on gluster is having issues - only preallocated can be created.

OK, Can we summarize it: 1. VDO must 'emulate512=true' 2. 'network.remote-dio' should be off ?

Re: Gluster VM image Resync Time
by Strahil 18 May '19

18 May '19

By default ovirt uses 'sharding' which splits the files into logical chunks. This greatly reduces healing time, as VM's disk is not always completely overwritten and only the shards that are different will be healed. Maybe you should change the default shard size.

Hello Community, Do you have any idea if SBD fencing mechanism will be implemented in the nearest future? It will be nice to be able to resset a host just like corosync/pacemaker cluster implementation.

Same here. The ssh host keys on our host nodes never change but there must be something in the ovirt database that needs to be updated.

Dropped RX Packets
by Magnus Isaksson 16 May '19

16 May '19

Hello all! I'm having quite some trouble with VMs that have a large amount of dropped packets on RX. This, plus customers complain about short dropped connections, for example one customer has a SQL server and an other serevr connecting to it, and it is randomly dropping connections. Before they moved their VM:s to us they did not have any of these issues. Does anyone have an idea of what this can be due to? And how can i fix it? It is starting to be a deal breaker for our customers on whether they will stay with us or not. I was thinking of reinstalling the nodes with oVirt Node, instead of the full CentOS, would this perhaps fix the issue? The enviroment is: Huawei x6000 with 4 nodes Each node having Intel X722 network card and connecting with 10G (fiber) to a Juniper EX 4600. Storage via FC to a IBM FS900. Each node is running a full CentOS 7.6 connecting to a Engine 4.2.8.2 Regards Magnus

Cluster Un-stable since power outage
by Alan G 16 May '19

16 May '19

Hi, We have a dev cluster running 4.2. It had to be powered down as the building was going to loose power. Since we've brought it back up it has been massively un-stable (Hosts constantly switching state, VMs migrating all the time). I now have one host running (with HE) and all others in maintenance mode. When I try activate another host i see storage errors in vdsm.log 2019-05-07 09:41:00,114+0000 ERROR (monitor/a98c0b4) [storage.Monitor] Error checking domain a98c0b42-47b9-4632-8b54-0ff3bd80d4c2 (monitor:424) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/storage/monitor.py", line 416, in _checkDomainStatus masterStats = self.domain.validateMaster() File "/usr/lib/python2.7/site-packages/vdsm/storage/sd.py", line 941, in validateMaster if not self.validateMasterMount(): File "/usr/lib/python2.7/site-packages/vdsm/storage/blockSD.py", line 1377, in validateMasterMount return mount.isMounted(self.getMasterDir()) File "/usr/lib/python2.7/site-packages/vdsm/storage/mount.py", line 161, in isMounted getMountFromTarget(target) File "/usr/lib/python2.7/site-packages/vdsm/storage/mount.py", line 173, in getMountFromTarget for rec in _iterMountRecords(): File "/usr/lib/python2.7/site-packages/vdsm/storage/mount.py", line 143, in _iterMountRecords for rec in _iterKnownMounts(): File "/usr/lib/python2.7/site-packages/vdsm/storage/mount.py", line 139, in _iterKnownMounts yield _parseFstabLine(line) File "/usr/lib/python2.7/site-packages/vdsm/storage/mount.py", line 81, in _parseFstabLine fs_spec = fileUtils.normalize_path(_unescape_spaces(fs_spec)) File "/usr/lib/python2.7/site-packages/vdsm/storage/fileUtils.py", line 94, in normalize_path host, tail = address.hosttail_split(path) File "/usr/lib/python2.7/site-packages/vdsm/common/network/address.py", line 43, in hosttail_split raise HosttailError('%s is not a valid hosttail address:' % hosttail) HosttailError: :/ is not a valid hosttail address: Not sure if it's related but since the restart the hosted_storage domain has been elected the master domain. I'm a bit stuck at the moment. My only idea is to remove HE and switch to a standalone Engine VM running outside the cluster. Thanks, Alan

[Users] Problem Creating "oVirtEngine" Machine

Modifying every box's or Virtual Machine's = HOSTS file with a FQDN and IP SHOULD work, but in my case it is not. = There are several reasons I've come to believe could be the problem = during my trial-and-errors testing and learning. FIRST - MACHINE IPs. THe machine's "Names" where not appearing in the Microsoft Active = Directory DHCP along with their assigned IPs; in other words, the DHCP = just showed an "Assigned IP", equal to the Linux Machine's IP, with a = <empty> ('i.e. blank, none, silch, plan old "no-letters-or-numbers") = "Name" in the "Name" (i.e. machines "network name", or FQDN-value used = by the Windows AD DNS-service) column. =20 if your IP is is appearing with an <empty> "name", there is no "host = name" to associate the IP, it makes it difficult to define a FQDN; which = isn't that useful if we're going to use the HOSTS files in all = participating machines in an oVirt Installation. I kept banging my head for three (3) long hours trying to find the = problem. In Fedora 18, I could't find where the "network name" of the machine = could be defined. =20 I tried putting the "Additional Search Domains" and/or "DHCP Client ID" = in Fedora's 18 Desktop - under "System Settings > Hardware > Network > = Options > IPv4 Setting" The DHCP went crazy; showing an "Aberrant-MAC-Address" (i.e. a really = long-sting value where the machine's MAC address should be), and we knew = the MAC address as we obtained using "ifconfig" on the machine getting = it's IP from the DHCP. So we reverted these entries from the = aforementioned, rebooted, and got an assigned IP, with proper MAC = address, but still no "Name" Kept wondering around the "Settings" and seeing which one made sense, = but what the heck, I went for it. =20 Under "System Settings > System > Details" I found the information about = GNOME and the machine's hardware. =20 There was a field for "Device Name" that originally had = "localhost.localdomain"; I changed the value to "ovirtmanager". and = under "Graphic" changed to "Forced Fallback Mode" to "ON". =20 I also installed all Kerberos libraries and client (i.e. authconfig-gtk, = authhub, authhub-client, krb5-apple-clents, krb5-auth-dialog, = krb5-workstation, pam-kcoda, pam-krb5, root-net.krb5) and rebooted VOILA=85!!! =20 I don;t know if it was the definition of "Device Name" from = "localhost.localdomain" to "ovirtengine", of the Kerberos libraries = install, or both. But finally the MS AD DHCP was showing the = Addigned-IP, the machine "Name" and the proper MAC-address. Regardless, = setting the machine's "Network Name" under "System Settings > System > = Details > Device Name", with no explanation of what "Device Name" meant = or was used for, was the last place I would have imagined this network = setting could be defined. NOTE - Somebody has to try the two steps I did together, separately. to = see which one is the real problem-solver; for me it is working, and "if = it ain't broke, don't fix it=85" Now that I have the DHCP / IP thing sorted, I have to do the DNS stuff. To this point, I've addressed the DHCP and "Network Name" of the = IP-Lease (required for the DNS to work). This still does't completely = explain why, by modifying the HOSTS file (allowing be to set and IP and = non-DNS FQDN). allows me to install the oVirtEngine "as long as I do not = use default HTTPd service parameters as suggested by the install". By = using the HOST file to "define" FQDNs, AND NOT using the default HTTPd = suggested changes, I'm able to install the oVirtEngine (given that I use = ports 8700 and 8701) to access the "oVirtEngine Welcome Screen", BUT = NONE of the "oVirt Portals" work=85 YET=85!!!
