VM "hot" RAM memory decrease
by Nicolás 29 Mar '17

29 Mar '17

Hi, I don't really know if this question is suitable on this list, as I doubt it's an oVirt bug, neither I know if it shall be considered a bug. We recently run a VM on a host that was memory over-used (around 80% of usage). The VM booted correctly, then we run "top" and saw how physical RAM started decreasing every two seconds. At first it was 4GB, then less and less until it stabilized at around 600MB. Based on this (correct me if I'm wrong), we believe this is an effect of having this VM with ballooning enabled, as it does exactly this: It adds/removes RAM depending on host decision. Thing is that this VM had a minimal guaranteed RAM of 1GB, so even if this happened due to ballooning, I'm not sure if it should have honored the minimum guaranteed RAM. When this happened, we run a 'ps' to see with what options the qemu process was invoked, and parameters seemed correct (that's why I don't know if it should be posted here or even if it's a bug). Is this the expected behavior? Thanks.

How to passthrough GPU to windows guest
by yimao 29 Mar '17

29 Mar '17

Hi, I'm trying to passthrough gpu card to windows 7 guest, but I got the error code 43. I use ovirt node: ovirt-node-ng-installer-ovirt-4.1-2017032304.iso and ovirt-engine-appliance-4.1-20170322.1.el7.centos.noarch.rpm I have added options "intel_iommu=on rdblacklist=nouveau pci-stub.ids=10de:1380,10de:0fbc" to the grub.conf and attached these devices to the guest. After I have installed the gpu's driver, I got the error code 43. Did I miss something? Any pointers or suggestions would be greatly appreciated. Thanks in advance. Yiimao Yang.

Introduction and initial help needed
by Abdullah 29 Mar '17

29 Mar '17

Hello It is Abdullah. I have been using different virtualization platform for a long time. Currently started working on oVirt. Initially I need some help with an issue: on the ovirt engine, I can add an ovirt-node 4.1 host but I cannot add a centOS 7.3 ovirt node. I have successfully installed the vdsm on the centos, but every time I try to add this host to engine, I get the following error: Command returned failure code 1 during SSH session 'root at my_host <http://lists.ovirt.org/mailman/listinfo/users>'. however an ovirt-node host installed from the ovirt-node iso works without any issue on the engine. Can anyone tell me what log output I need to provide to find out the reason.

Setting up hosted engine appliance on a bonded interface
by Bryan Sockel 29 Mar '17

29 Mar '17

Hi, I am attempting to deploy an appliance to a bonded interface, and i getting this error when it attempts to setup the bridge: [ ERROR ] Failed to execute stage 'Misc configuration': Failed to setup networks {'ovirtmgmt': {'bonding': 'bond0', 'ipaddr': u'10.20.101.181', 'netmask': u'255.255.255.0', 'defaultRoute': True, 'gateway': u'10.20.101.1'}}. Error code: "-32603" message: "Attempt to call function: <bound method Global.setupNetworks of <API.Global object at 0x39c9110>> with arguments: ({u'ovirtmgmt': {u'bonding': u'bond0', u'ipaddr': u'10.20.101.181', u'netmask': u'255.255.255.0', u'defaultRoute': True, u'gateway': u'10.20.101.1'}}, {}, {u'connectivityCheck': False}) error: 'NoneType' object is not iterable" Is it possible to deploy an appliance to a network bond? My Network guy has configured my ports in the switch so i can connect via bonded links. however, if the interfaces are not bonded, it will suspend the links.

How to re-initialize storage?
by Peter Wood 28 Mar '17

28 Mar '17

Hi, I inherited a small oVirt cluster with 3 nodes using iSCSI storage. The LUNs used by the oVirt nodes were also accessible by some VMware nodes. By mistake an action was started on VMware to initialize and start using the same LUNs, which it happily did. This rendered the storage no longer usable by oVirt nodes. All VMs went down, their image files no longer accessible, the whole cluster became unusable without access to the shared storage. We have recovered from backups and moved the VMs to another cluster and now I want to get this oVirt cluster back up and running. I'm not an oVirt expert so everything I tried was through the web interface and everything failed because storage is not accessible. I can't remove VMs, I can't remove nodes, I can't remove the storage domain. What is the right approach to destroy the cluster and rebuild it and re-initialize the storage? Even better if I can just remove all VMs from the inventory and somehow tell it to make the storage LUNs usable again? Any help is highly appreciated? Thank you, -- Peter

problems with serial console in 4.1.1

Hello, trying serial console in 4.1.1 I have some problems. I have not understood if it depends on my client, or the guest or oVirt... My client is Fedora 25 updated My guest is a CentOS 7.3 VM updated (my latest successful attempts were when in 7.2) My oVirt is 4.1.1 (my latest successful attempts were when in 4.0.x) Some tests $ ssh -i .ssh/id_dsa.pub ovirt-vmconsole@ovmgr1 -p 2222 Available Serial Consoles: 00 c7service[2e571c77-bae1-4c1c-bf98-effaf9fed741] 01 c7testovn1[63818176-cfb5-4a00-912d-ce0e812be76c] 02 c7testovn2[f00c8f30-a658-4a18-bf85-3b523de93183] 03 dbatest6[633b58b6-5e99-491b-a312-0976d4e8d979] 04 nas4free[6b9013d1-1837-4b0f-aa34-c9130d4f1229] 05 raclab1[1775d180-288d-4116-af1e-d90b2989cb8a] 06 raclab2[852aa8b1-a3e2-4658-be91-0ab51b6b7260] SELECT> 00 and it stays here without giving the os prompt. In 7.3 guest I have VirtIO serial console enabled and this situation [root@c7service ~]# cat /proc/cmdline BOOT_IMAGE=/vmlinuz-3.10.0-514.6.1.el7.x86_64 root=/dev/mapper/cl-root ro rd.lvm.lv=cl/root rd.lvm.lv=cl/swap rhgb quiet console=ttyS0 [root@c7service ~]# [root@c7service ~]# ps -ef|grep agetty root 718 1 0 11:15 ttyS0 00:00:00 /sbin/agetty --keep-baud 115200 38400 9600 ttyS0 vt220 root 1760 1541 0 11:29 pts/0 00:00:00 grep --color=auto agetty [root@c7service ~]# So it seems ok.

Hi, I've just migrated to 4.1 and I find changing a running vm name into webadmin needs the vm to be rebooted to take effect. I've done this action many times in the previous version without rebooting, is it a RFE or a bug? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr
