Host install failed - cannot set maintenance or remove
by Callum Smith
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

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
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.
Nicolas VAYE

How to update "quota_cluster_limit" settings of a quota object through REST API?
by Shao-Da Huang
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-0253-0015-02...
<?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-0253-0015-02...
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
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
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

Re-attaching ISOs and moving ISOs storage

Content-Type: text/plain; charset="us-ascii"

Dear All,
It appears that clicking "detach" on the ISO storage domain is a really bad=
idea. This has gotten half way through the procedure and now can't be reco=
vered from. Is there any advice for re-attaching the ISO storage domain man=
ually? An NFS mount didn't add it back to the "pool" unfortunately.
On a separate note, is it possible to migrate this storage to a new locatio=
n? And if so how.
Regards,
Callum
