Windows VM always growing
by Thomas Fecke 14 Nov '18

14 Nov '18

Hey Guys, we use, for our Windows VMs, "thin Provision". The Problem: the Disk always grow but if I delete Files in Windows the actual Disk size stays the same. Any way to get the "real" Windows Size back again? Some VMs got an Actual Size from about 100 GB - but Windows just got 25 GB Thanks in advanced Thomas

Engine trying to activate already activated hosts, causing serious instability...
by Jason P. Thomas 14 Nov '18

14 Nov '18

I've got a 4 node cluster running oVirt 4.2.7. 3 hosts are hyperconverged with glusterfs. Engine is running on one of the gluster volumes. Since yesterday, the cluster is completely unstable and will not reliably run VMs including the Engine. A notification will pop up in the WebUI stating "Finished invoking activate on host ovirt1" while the task list indicates "Activating host ovirt1". When this task ultimately fails, the node in question goes NonOperational. All our VMs have been down since 3pm yesterday, so help is greatly appreciated. Sincerely, Jason

LDAP Bind failing because of SSLHandshakeException after Virtualization Manager was rebooted
by wbhegedus＠gmail.com 14 Nov '18

14 Nov '18

After moving and rebooting our Red Hat Virtualization Manager box to another node in our cluster, we are unable to make LDAP login work using StartTLS. No networking or configuration changes were made, but the logs indicate that the TLS negotiation is failing with our Active Directory domain controllers now. Specifically: "2018-11-13 10:33:12,500-05 WARN [org.ovirt.engineextensions.aaa.ldap.Framework] (ServerService Thread Pool -- 49) [] Exception: The connection reader was unable to successfully complete TLS negotiation: SSLHandshakeException(sun.security.validator.ValidatorException: No trusted certificate found), ldapSDKVersion=4.0.5, revision=b28fb50058dfe2864171df2448ad2ad2b4c2ad58" I have tried everything I can think of. I removed and reimported the certificate for the domain controller in the Java Keystore. I deleted the profile entirely and recreated it. I tried using the full certificate chain and I tried using single certificates from the chain, and all combinations together. For now, we have it working by specifying "pool.default.ssl.insecure = true" in the .properties file, but I'd prefer to have this working again using StartTLS. Is there something I am missing? I want to make sure that I'm not overlooking something before submitting any sort of bug report. Any help is appreciated. Thanks! PS - this is what the properties file looks like: [root@rhvm ~]# cat /etc/ovirt-engine/aaa/liberty.edu.properties include = <ad.properties> vars.domain = liberty.edu vars.user = cn=PREADER,ou=Service Accounts,ou=IS,OU=FSA,dc=University,dc=liberty,dc=edu vars.password = <redacted> pool.default.auth.simple.bindDN = ${global:vars.user} pool.default.auth.simple.password = ${global:vars.password} pool.default.serverset.type = srvrecord pool.default.serverset.srvrecord.domain = ${global:vars.domain} pool.default.ssl.startTLS = true pool.default.ssl.truststore.file = ${local:_basedir}/liberty.edu.jks

Replicated storage gets erased when added to new environment.
by Jacob Green 14 Nov '18

14 Nov '18

So I was testing with two Identical ovirt environments running the latest 4.2 environment. I have iscsi storage set up at Site A, and I have that same storage replicated to Side B, before I get into learning disaster recovery I wanted to see what importing the replicated storage would look like. However when I import it I get the follow, and the vms are wiped from the replicated storage I presented with iscsi. So is this possible with iscsi? Is there another way to go about doing this? My iscsi solution is freenas. -- Jacob Green Systems Admin American Alloy Steel 713-300-5690

Networking - interface and security questions
by davidk＠riavera.com 14 Nov '18

14 Nov '18

Hello, I'm trying to setup a new ovirt install and have run into some general issues that I hope someone can help with. I'm somewhat new to ovirt (but not virtualization). First off, I've been doing lots of reading and I can't seem to find what the generally accepted method is for firewalling access between networks and VMs is in ovirt? I see references to network filters, but no obvious ways to set ports or modify the configuration beyond a set list of general good-practice policies (no arp spoofing, etc). What do people use in a production environment? Trunk out to an external firewall and do the filtering there? Run iptables or some rules locally in each VM? Or just run pfSense or other firewall software as another VM and manage it there? And lastly, I'm trying to setup a new interface using the external ovn provider but am having problems. I can define the external provider network just fine (not connected to physical network), but can't seem to actually use it. When I create a new VM and assign the new network to an associated interface, the VM fails to start. The error I get is: "VM testvm is down with error. Exit message: Cannot get interface MTU on 'br-int': No such device." Am I missing something obvious here? I'm running oVirt 4.2.7 with the latest oVirt Node on a few hosts (also 4.2.7). All my configuration has been via the web interface so far. Sincerely,

RDP as default console for Windows VM
by Anantha Raghava 14 Nov '18

14 Nov '18

Hi, In the past, we could set RDP as default console for Windows VM. VMs used to reboot once we set RDP under console options & become default for all users. In the new versions I am unable to achieve the same result. Is there a way to set RDP as default Console for Windows VM? -- Thanks & Regards, Anantha Raghava eXzaTech Consulting And Services Pvt.

Ovirt VDI
by Hari Prasanth Loganathan 14 Nov '18

14 Nov '18

Hi Team, I created a VM which has one disk. For this VM, I created two Virtual Desktop (VDI_1 and VDI_2) using open-UDS and it created successfully. *Consider the following scenario* : 1) I took a console for VDI_1 and created a file in it using the console 2) I took the console for VDI_2 and checked whether the file created in VDI_1 is available in it but as per the VDI concept it is not available Could someone clarify the below use case, Now when I looked at the Disk associated with the VDI, It seems the Disk of the VM is same for the VDI_1 and VDI_2, so How does the file created in VDI_1 is not reflecting in VDI_2?
