[OT] transferring kvm raw mage from filesystem to lvm based
by Gianluca Cecchi
Hello,
I have a windows 7 VM that is composed by a raw disk on filesystem on
Fedora 28.
I would like to transfer this VM to another environment, always based on
same version of Fedora 28, but where the storage is configured in
virt-manager as lvm based, so similar to what happens in oVirt block based
storage domains.
I'm trying to figure how to transfer the image.
I presume I can create a new LV and then leave some bytes for the LVM
header into the created LV and then make a sort of dd with offset?
Anyone has any hint?
Thanks in advance,
Gianluca

iSCSI multipath with Dell Compellent
by Bernhard Dick
Hi,
I'm trying to achieve iSCSI multipathing with an Dell Compellent SC4020
array. As the Dell Array does not work as an ALUA system it displays
available LUNs only on the currently active system (here is a good
description that I found:
https://niktips.wordpress.com/2016/05/16/dell-compellent-is-not-an-alua-s...
). As a result I cannot add the currently non-active controller to an
iSCSI-Bond (as it does not present the LUNs to oVirt) and so the path to
the second controller will not be up. Is there any way to solve this?
Regards

Change network interface for hosted engine iSCSI connection
by Bernhard Dick
Hi,
after I changed the network configuration of one of my hosted engine
hosts in oVirt I am no longer able to run the ha-daemon on the host.
When I run hosted-engine --connect-storage on this host I get the
following error:
vdsm.client.TimeoutError: Request StoragePool.connectStorageServer with
args {'connectionParams': [{'netIfaceName': 'ens1f1', 'port': '3260',
'connection': '192.168.1.1', 'iqn': 'iqn.2002-03.com.compellent:5000
d...', 'user': '', 'tpgt': '0', 'ifaceName': 'ens1f1', 'password': '',
'id': 'cd5fa13f-fbb7-4cc6-a094-4b280dc7b514'}], 'storagepoolID':
'00000000-0000-0000-0000-000000000000', 'domainType': 3} timed out
after 60 seconds
ens1f1 is the network card that has been used earlier for iSCSI, now it
should connect via ens1f0. Is there a way to update this configuration
for the host?

I already already found out that there might be a bug in some older versions of openshift/ansible but the recent versions should be fine.
Thanks for any suggestions on this!

Trouble to update the ovirt hosts (and solution)
by Arman Khalatyan
Current cocpit packages are conflicting, which is preventing the host update:
....
Transaction check error:
file /usr/share/cockpit/networkmanager/manifest.json from install of
cockpit-system-176-2.el7.centos.noarch conflicts with file from
package cockpit-networkmanager-172-1.el7.noarch
file /usr/share/cockpit/networkmanager/po.ca.js.gz from install of
cockpit-system-176-2.el7.centos.noarch conflicts with file from
package cockpit-networkmanager-172-1.el7.noarch
....
Looks like a current packaging of cocpit is wrong, it doesn't upgrade
existing version.
To solve it simply:
yum remove cockpit-networkmanager-172-1.el7.noarch
yum clean ;yum update
all fixed.

clarification needed on power management options
by g.vasilopoulos＠uoc.gr
I would like some clarification on MinFreeMemoryForUnderUtilized and MaxFreeMemoryForOverUtilized.
How does that work? it seems the names should be oposite ?
so if I have hosts with 64GB ram and I want to consider them over utilized at 48GB used and under utilized at 12GB used, should I set
MinFreeMemoryForUnderUtilized=12GB
MaxFreeMemoryForOverUtilized=48GB ?
is this correct ?
Also If ihave hyperconverged setup with 3 hosts having a replica3 storage for the engine and I disable policy management on these hosts, will these hosts be part of the overall utilization regardless if the
engine can shut them down ?

liveliness check fails on one host
by g.vasilopoulos＠uoc.gr
I have an ovirt installation (4.2.6), and I have come accross this issue:
Hosted engine can migrate to a certain host say host5. Admin portal is working fine, everything is working fine AFAIK but hosted-engne --vm-status shows "failed livelines check", when engine is on that host, so after a while the engine migrates somewhere else, it not a terrible problem, but it is annoying and I would like to know why is this happening, and if there is a way to fix it
On every other host in the cluster this problem does not exists. firewall rules are exactly the same on hosts (in fact they are copied) . Any places to look at?
Thank you
