Re: DHCP Client in Guest VM does not work on ovirtmgmt
by Strahil 07 Nov '19

All my VMs are using DHCP over ovirtmgmt network. So, yes it should be possible. Are yoiu sure that your hosts' network is in sync ?

CPU Pinning topology
by Fabrice Bacchella 07 Nov '19

07 Nov '19

I'm trying to understand the field "CPU Pinning topology" in the "Ressource Allocation" tab, that looks it needed by High Performance VM. I have this hardware: # lscpu Architecture: x86_64 CPU(s): 48 On-line CPU(s) list: 0-47 Thread(s) per core: 2 Core(s) per socket: 12 Socket(s): 2 NUMA node(s): 2 And I want to run a 22 vCPU vm on it, so no SMT, and 11 vCPU mapped to each socket. The only explanation I found about this field content was here: https://rhv.bradmin.org/ovirt-engine/docs/Virtual_Machine_Management_Guide/… and I can wrap my head around it. Do I need to given explicit mapping for all the 22 vCPU ? And dig in lscpu -e or numactl -H to find how each pCPU is identified ?

Can ovirt-node support multiple network cards ？

Can ovirt-node support multiple network cards ？ I download ovirt-node-ng-installer-4.3.5-2019073010.el7.iso from ovirt site. And install on a Dell R730 Server. The version of ovirt-engine is 4.3.5.5. I found that the logic network ovirtmgmt can only point to one network card interface. Can ovirt-node support multiple network cards ？ If yes , please tell me the method.

How to pass parameters between VDSM Hooks domxml in single run
by Vrgotic, Marko 06 Nov '19

06 Nov '19

Dear oVIrt, A while ago we discussed on ways to change/update content of parameters of domxml in certain action. As I mentioned before, we have added the VDSMHook 60_nsupdate which removes the DNS record entries when a VM is destroyed: … domxml = hooking.read_domxml() name = domxml.getElementsByTagName('name')[0] name = " ".join(name.nodeValue for name in name.childNodes if name.nodeType == name.TEXT_NODE) nsupdate_commands = """server {server_ip} update delete {vm_name}.example.com a update delete {vm_name}. example.com aaaa update delete {vm_name}. example.com txt send """.format(server_ip="172.16.1.10", vm_name=name) … The goal: However, we did not want to execute remove dns records when VM is only migrated. Since its considered a “destroy” action we took following approach. * In state “before_vm_migrate_source add hook which will write flag “is_migration” to domxml * Once VM is scheduled for migration, this hook should add the flag “is_migration” to domxml * Once 60_nsupdate is triggered, it will check for the flag and if there, skip executing dns record action, but only remove the flag “is_migration” from domxml of the VM … domxml = hooking.read_domxml() migration = domxml.createElement("is_migration") domxml.getElementsByTagName("domain")[0].appendChild(migration) logging.info("domxml_updated {}".format(domxml.toprettyxml())) hooking.write_domxml(domxml) … When executing first time, we observed that flag “ <name>hookiesvm</name> <uuid>fcfa66cb-b251-43a3-8e2b-f33b3024a749</uuid> <metadata xmlns:ns0="http://ovirt.org/vm/tune/1.0" xmlns:ns1="http://ovirt.org/vm/1.0"> <ns0:qos/> <ovirt-vm:vm xmlns:ovirt-vm="http://ovirt.org/vm/1.0"> <ovirt-vm:clusterVersion>4.3</ovirt-vm:clusterVersion> <ovirt-vm:destroy_on_reboot type="bool">False</ovirt-vm:destroy_on_reboot> <ovirt-vm:launchPaused>false</ovirt-vm:launchPaused> <ovirt-vm:memGuaranteedSize type="int">1024</ovirt-vm:memGuaranteedSize> <ovirt-vm:minGuaranteedMemoryMb type="int">1024</ovirt-vm:minGuaranteedMemoryMb> ...skipping... <address bus="0x00" domain="0x0000" function="0x0" slot="0x09" type="pci"/> </rng> </devices> <seclabel model="selinux" relabel="yes" type="dynamic"> <label>system_u:system_r:svirt_t:s0:c169,c575</label> <imagelabel>system_u:object_r:svirt_image_t:s0:c169,c575</imagelabel> </seclabel> <seclabel model="dac" relabel="yes" type="dynamic"> <label>+107:+107</label> <imagelabel>+107:+107</imagelabel> </seclabel> <is_migration/> </domain> is added to domxml, but was present once 60_nsupdate hook was executed. The question: How do we make sure that, when domxml is updated, that the update is visible/usable by following hook, in single run? How to pass these changes between hooks? Kindly awaiting your reply. — — — Met vriendelijke groet / Kind regards, Marko Vrgotic

Hi, as part of the 4.4 development we'd like to ask for testing current master. In order to ease the test, you can take: oVirt Node: https://resources.ovirt.org/pub/ovirt-master-snapshot/iso/ovirt-node-ng-ins… when this link won't be available anymore due to nightly build rotation you can take the latest from https://resources.ovirt.org/pub/ovirt-master-snapshot/iso/ovirt-node-ng-ins… oVirt appliance: https://resources.ovirt.org/pub/ovirt-master-snapshot/rpm/el8/x86_64/ovirt-… as per oVirt Node, you can take the latest from https://resources.ovirt.org/pub/ovirt-master-snapshot/rpm/el8/x86_64/ if above link doesn't work. The above 2 builds have been tested on a single host nested VM system with 70Gb disk, 8Gb of RAM and 4 cores for the node. Both oVirt Node and oVirt Engine appliance installation succeeded on 80GB NFS external storage with static IP addressing. We have a known issue on booting with more than 1 NIC that will be addressed soon, so please use a single NIC in your tests for now. Looking forward for your feedback, thanks. -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://www.redhat.com/>*Red Hat respects your work life balance.

Hi Dominik, I think I found it - it seems that for some reason my gateway is missing in 'ip route'. Running 'ifdown ovirtmgmt; ifup ovirtmgmt' fixes it, which proves that network scripts read properly the ifcfg-ovirtmgmt file. Do you have any idea where to look for?

Self-Hosted Engine + vxlan + networkd
by pavel＠gremwell.com 04 Nov '19

04 Nov '19

Dear oVirt Community, It appears that oVirt self-hosted engine does not support network configurations based on systemd-networkd? Am I correct? Does oVirt self-hosted engine deployment support VXLAN interface to configure "ovirtmgmt" on top of it? My setup: - three bare-metal servers: two of them are CentOS 7 based, clean installation. the third one is Ubuntu based served as a storage. - all three of them have public Internet connectivity, via basic Ethernet. - in order to emulate internal network, VXLAN was configured between those three. Mainly for testing purposes. - network configuration was done using systemd-networkd, internal communications worked fine. - DNS server was configured on this internal network. worked as direct/reverse resolver. Thus, the main host which I tried to convert to self-hosted engine following https://www.ovirt.org/documentation/self-hosted/chap-Deploying_Self-Hosted_… guide, has the following network interfaces (redacted): - eth0, static IPv4, connected to the Internet; - vxlan0, on top of eth0, has private IPv4, 192.168.200.1; - hosts names resolve via private VXLAN network using 192.168.200.254. I started deployment saying that: Engine FQDN:ovirt-e1.example.com Network Configuration:Static VM IP Address:192.168.200.250/24 Gateway Address:192.168.200.1 DNS Servers:192.168.200.254 hostname of this host on the management network: ovirt-h1.example.com Deployment fails with error "Host ovirt-h1.example.com installation failed. Failed to configure management network on the host." After failure the system (host) does not have "ovirtmgmt" bridge. The same situation was when the host moved from networkd configuration to "network-scripts" (with VXLAN support added). I suspect that the root cause of the problem is that ansible scenarios were not able to create "ovirtmgmt" bridge on top of vxlan0. No switching to VLAN-based management interface... (did not actually tried yet).

While trying to deploy using the WEB UI for single hyperconverged setup I run into this issue (ovirt 4.3.5, ovirt 4.3.6). mount point is "/gluster_bricks/engine" however "/gluster_bricks/engine/engine" is not created. Read a post about gluster 6.1 and having to add /gluster_bricks/engine/.glusterfs/indices manually, I tried it but it did not work, I could not deploy the hosted engine vm.

Re: [ANN] oVirt 4.3.7 First Release Candidate is now available for testing
by Strahil 02 Nov '19

02 Nov '19

I think I have a theory about ovirt1 , but I have to test it. 1. Ovirt1 has a team device controlled by NetworkManager , but in engine those interfaces are unused 2. I guess that when I recently 'reinstalled' the host from UI, the old teamports' ifcfg-<DEVICENAME> was moved to ifcfg-<DEVICENAME>-1 and the original file was left empty. 3. When the system rebooted, network.service rereads all ifcfg-* files and starts the team0 , but when NetworkManager reads the empty files - he alters the /etc/resolv.conf which leads to out-of-sync status. Still, this is only theory and as ovirt3 has no team device (plain gluster arbiter) - I'm not sure how close is this one.

How to change the CPU of the win10 virtual machine on ovirt-node from 2 cores to 8 cores?
by wangyu13476969128＠126.com 02 Nov '19

02 Nov '19

The version of The ovirt-engine is 4.3.5. I created a win10 virtual machine on ovirt-node, which is allocated 8 cores, and when using the virtual machine I found only 2 cores. I used the command "virsh edit win10" on ovirt-node to prepare to modify the CPU core. I was prompted to enter my username and password. I entered the username and password of the ovirt-engine web interface and ssh log in to the ovirt-node username root and password, but both prompt: Error: failed to connect to the hypervisor Error: authentication failed: authentication failed How can this problem be solved?

Ssh to host and check the status of : sanlock.service supervdsmd.service vdsmd.service ovirt-ha-broker.service ovirt-ha-agent.service For example if sanlock is working, but supervdsmd is not - try to restart it. If it fais, run: systemctl cat supervdsmd.service And execute the commands in sections: ExecStartPre ExecStart And report any issues, then follow the next service in the chain.
