Host install failed - cannot set maintenance or remove
by Callum Smith 09 May '18

09 May '18

Dear All, There appears to be an issue with the host install on these, there's quite a lot of errors being kicked out into the logs as they cycle through attempting to activate, failing, and then failing to go into maintenance. I can't remove the hosts from the engine to attempt to reinstall them. Issue presented from having a statically configured network on the ovritmgmt network on the hosts before running the host install. There are SQL errors (FK missing) and assorted goodness in there. Any help greatly appreciated, not sure what the next step forward is from here Engine.log on dropbox: https://www.dropbox.com/s/82iem0ov869yh32/engine.log-20180508.zip?dl=0 PS. Sorry if this comes through a few times, mailing list membership seems to be having a funny turn this morning.

how to attach an export domain to a new datacenter with an export domain not very well unattached from an obsolete datacenter
by Nicolas Vaye 09 May '18

09 May '18

Hi Ovirt Team, how to attach an export domain to a new datacenter with an export domain not very well unattached from an obsolete datacenter ? My old platform with ovirt 4.1 was deleted ans reinstalled with ovirt 4.2.3. It's ok but i have a problem with an export domain which has not been unattached before the extinction of the old platform. When i try to attach this export domain, i have the error message in the gui : Failed to attach Storage Domain oVirtNFS_EXPORT to Data Center xxx. How can i reinitialize the export domain without erase the data ? just the manager who own the domain. Thanks for all.

How to update "quota_cluster_limit" settings of a quota object through REST API?
by Shao-Da Huang 09 May '18

09 May '18

Hi, I can update the vCPU and memory quota by editing a Quota object of a datacenter through webadmin portal, but it seems that I cannot update through REST API... For example, I have a quota object with a global quota_cluster_limit object: GET https://192.168.80.168/ovirt-engine/api/datacenters/5ad4fafe-0253-0015-0215… <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <quota_cluster_limits> <quota_cluster_limit href="/ovirt-engine/api/datacenters/5ad4fafe-0253-0015-0215-000000000378/quotas/8a6b3336-2dfc-4e40-a58e-9bdcb45d228a/quotaclusterlimits/8a6b3336-2dfc-4e40-a58e-9bdcb45d228a" id="8a6b3336-2dfc-4e40-a58e-9bdcb45d228a"> <memory_limit>16.0</memory_limit> <memory_usage>0.0</memory_usage> <vcpu_limit>6</vcpu_limit> <vcpu_usage>0</vcpu_usage> <quota href="/ovirt-engine/api/datacenters/5ad4fafe-0253-0015-0215-000000000378/quotas/8a6b3336-2dfc-4e40-a58e-9bdcb45d228a" id="8a6b3336-2dfc-4e40-a58e-9bdcb45d228a"/> </quota_cluster_limit> </quota_cluster_limits> But when I try to do PUT https://192.168.80.168/ovirt-engine/api/datacenters/5ad4fafe-0253-0015-0215… with request body like: <quota_cluster_limit> <vcpu_limit>8</vcpu_limit> </quota_cluster_limit> I got *405 Method Not Allowed.* Could anyone give me some advices?

newbie questions on networking
by Rue, Randy 08 May '18

08 May '18

Hi All, I'm new to oVirt and have set up a basic cluster of an engine and five hosts, using the quick start and default settings as much as possible. I confess it's taken some heavy flailing to get this far, the docs all seem to be for the previous versions and the latest greatest appears to be significantly different. I now have a working data center / cluster /hosts and a bouncing baby ubuntu server LTS VM. My VM is getting a DHCP address and nameservers from the data center the hosts sit in. But from the VM I can only ping the IP of the host the VM is on. Can't reach the gateway of the local subnet, or anything in the real world. Am I missing some step? the "Quick Start" doesn't say much beyond "The ovirtmgmt Management network is used for this document, however if you wish to create new logical networks see the oVirt Administration Guide." The admin guide has information on creating new networks but I'm not spotting the parts I need to connect my VM to the real world. Or how to attach another network to the host if all NICs are in use. Short Version: * Is some change needed to allow VMs on the ovirtmgmt network to connect to the real world? If so, what? * Is the ovirtmgmt network not meant for "commodity" use, and instead I should have some other network? If so, how do I connect that to the real LAN/WAN, and how do I replace the ovirtmgmt with it? (my hosts each only have two NICs bonded in a pair). Hope to hear from you, Randy in Seattle

Problems with OVN
by Samuli Heinonen 08 May '18

08 May '18

Hi all, I'm building a home lab using oVirt+GlusterFS in hyperconverged(ish) setup. My setup consists of 2x nodes with ASRock H110M-STX motherboard, Intel Pentium G4560 3,5 GHz CPU and 16 GB RAM. Motherboard has integrated Intel Gigabit I219V LAN. At the moment I'm using RaspberryPi as Gluster arbiter node. Nodes are connected to basic "desktop switch" without any management available. Hardware is nowhere near perfect, but it get its job done and is enough for playing around. However I'm having problems getting OVN to work properly and I'm clueless where to look next. oVirt is setup like this: oVirt engine host oe / 10.0.1.101 oVirt hypervisor host o2 / 10.0.1.18 oVirt hypervisor host o3 / 10.0.1.21 OVN network 10.0.200.0/24 When I spin up a VM in o2 and o3 with IP address in network 10.0.1.0/24 everything works fine. VMs can interact between each other without any problems. Problems show up when I try to use OVN based network between virtual machines. If virtual machines are on same hypervisor then everything seems to work ok. But if I have virtual machine on hypervisor o2 and another one on hypervisor o3 then TCP connections doesn't work very well. UDP seems to be ok and it's possible to ping hosts, do dns & ntp queries and so on. Problem with TCP is that for example when taking SSH connection to another host at some point connection just hangs and most of the time it's not even possible to even log in before connectiong hangs. If I look into tcpdump at that point it looks like packets never reach destination. Also, if I have multiple connections, then all of them hang at the same time. I have tried switching off tx checksum and other similar settings, but it didn't make any difference. I'm suspecting that hardware is not good enough. Before investigating into new hardware I'd like to get some confirmation that everything is setup correctly. When setting up oVirt/OVN I had to run following undocumented command to get it working at all: vdsm-tool ovn-config 10.0.1.101 10.0.1.21 (oVirt engine IP, hypervisor IP). Especially this makes me think that I have missed some crucial part in configuration. On oVirt engine in /var/log/openvswitch/ovsdb-server-nb.log there are error messages: 2018-05-06T08:30:05.418Z|00913|stream_ssl|WARN|SSL_read: unexpected SSL connection close 2018-05-06T08:30:05.418Z|00914|jsonrpc|WARN|ssl:127.0.0.1:53152: receive error: Protocol error 2018-05-06T08:30:05.419Z|00915|reconnect|WARN|ssl:127.0.0.1:53152: connection dropped (Protocol error) To be honest, I'm not sure what's causing those error messages or are they related. I found out some bug reports stating that they are not critical. Any ideas what to do next or should I just get better hardware? :) Best regards, Samuli Heinonen

oVirt and Oracle Linux support

Hi, I'm new to this ML. I started to play a bit with oVirt and I saw that you actually support RH and CentOS. Is there any plan to also support Oracle Linux ? I had to fight so much to get everything on OL correctly running. Thanks Simon
