Recovering hosted-engine
by Andrew Dent 02 Jul '17

--------=_MB617458AF-4FCC-4AB6-8A34-3338D99C6BB8 Content-Type: text/plain; format=flowed; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hi A couple of questions about hosted-engine recovery. Part way through this URL, in the section "Workflow for Restoring the=20 Self-Hosted Engine Environment" http://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restorin= g_an_EL-Based_Self-Hosted_Environment/ it looks like once the hosted-engine is recovered on Host 1, the VMs on=20 Host 2 and 3 will be running, but not accessible to the recovered Hosted=20 Engine. Is that correct? If so, how to you remove host 2 and host 3 from the environment, then=20 add back in again while keeping the VMs running? Host 2 and Host 3 are not recoverable in their current state. These=20 hosts need to be removed from the environment, and then added again to=20 the environment using the hosted-engine deployment script. For more=20 information on these actions, see the Removing Non-Operational Hosts=20 from a Restored Self-Hosted Engine Environment section below and Chapter=20 7: Installing Additional Hosts to a Self-Hosted Environment=20 <http://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restori= ng_an_EL-Based_Self-Hosted_Environment/chap-Installing_Additional_Hosts_to_= a_Self-Hosted_Environment>.

oVirt Node update not updating kernel, glibc, etc
by Mike DePaulo 02 Jul '17

02 Jul '17

Hi, I installed 3 ovirt 4.1.1 nodes in early May. Today used oVirt's webgui to update ("Upgrade") 2 of them. They are both reporting oVirt Node 4.1.2 & vdsm-4.19.15-1.el7.centos now. However, it appears that the kernel was not updated: [root@death-star peers]# uname -a Linux death-star 3.10.0-514.16.1.el7.x86_64 #1 SMP Wed Apr 12 15:04:24 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux And neither was glibc The installed version is still 2.17-157.el7_3.1 rather than 2.17-157.el7_3.4 . The following lines were appended to /var/log/yum.log: Jul 01 18:47:49 Installed: ovirt-node-ng-image-4.1.2-1.el7.centos.noarch Jul 01 18:50:27 Installed: ovirt-node-ng-image-update-4.1.2-1.el7.centos.noarch Jul 01 18:50:27 Erased: ovirt-node-ng-image-update-placeholder-4.1.1.1-1.el7.centos.noarch Thanks in advance, -Mike

Re: [ovirt-users] [ovirt-devel] problem about vm in ovirt node can ping node, but cannot ping gateway or the third host in LAN
by Edward Haas 01 Jul '17

01 Jul '17

If I understood correctly, you are using a nested solution where the node is itself a VM. If this is the case, you may have a security feature active on the physical host/node. In oVirt we have the default filter which allows only a single source mac to exit the vNIC, but you disabled it. I guess you should have something similar on the upper node. Please note that such topics fit the user list, not devel. Thanks, Edy.

HostedEngine VM not visible, but running
by cmc 30 Jun '17

30 Jun '17

Hi, I've migrated from a bare-metal engine to a hosted engine. There were no errors during the install, however, the hosted engine did not get started. I tried running: hosted-engine --status on the host I deployed it on, and it returns nothing (exit code is 1 however). I could not ping it either. So I tried starting it via 'hosted-engine --vm-start' and it returned: Virtual machine does not exist But it then became available. I logged into it successfully. It is not in the list of VMs however. Any ideas why the hosted-engine commands fail, and why it is not in the list of virtual machines? Thanks for any help, Cam

vm shutdown long delay is a problem for users of pools
by Paul 30 Jun '17

30 Jun '17

This is a multipart message in MIME format. ------=_NextPart_000_0079_01D2EB83.89CE5690 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Hi, Shutting down VM's in the portal with the red downfacing arrow takes quite some time (about 90 seconds). I read this is mainly due to a 60 second delay in the ovirt-guest-agent. I got used to right-click and use "power off" instead of "shutdown", which is fine. My users make use of VM in a VM-pool. They get assigned a VM and after console disconnect the VM shuts down (default recommended behavior). My issue is that the users stays assigned to this VM for the full 90 seconds and cannot do "power off". Suppose he disconnected by accident, he has to wait 90 seconds until he is assigned to the pool again until he can connect to another VM. My questions are: - Is it possible to decrease the time delay of a VM shutdown? 90 seconds is quite a lot, 10 seconds should be enough - Is it possible for normal users to use "power off"? - Is it possible to "unallocate" the user from a VM if it is powering down?

Unable to rename disks via REST API
by Bruno Rodriguez 30 Jun '17

30 Jun '17

Hello everyone, I'm having some problems about renaming some disks (setting a different alias, name or description) for VMs disks created from a template. When I get this URL https://ovirt-manager/ovirt-engine/api/disks/0123 I can see are the methods sparsify, export, move and copy. I tried to POST the following XML to the previous URL with no result (as expected, it won't work) <disk> <alias>my_machine_Disk1</alias> </disk> I'm quite sure I'm thinking about it in a wrong way (as usual). Any help would be welcome... Thank you in advance -- Bruno Rodríguez Rodríguez *Port d'Informació Científica (PIC)*

Moving thin provisioned disks question
by Gianluca Cecchi 29 Jun '17

29 Jun '17

Hello, I have a storage domain that I have to empty, moving its disks to another storage domain, Both source and target domains are iSCSI What is the behavior in case of preallocated and thin provisioned disk? Are they preserved with their initial configuration? Suppose I have one 500Gb thin provisioned disk Why can I indirectly see that the actual size is 300Gb only in Snapshots tab --> Disks of its VM ? Thanks, Gianluca

Hi All, I have Ovirt 4.1 with 3 nodes on top glusterfs, all are running smoothly except USB redirection. I Have 2 VMs: - Windows 2016 64bit - Windows 10 64bit Although both are able to see USB have attached issue. On Past when testing on Windows 7 VM USB redirection was running smoothly. Can i have your suggestion on this issue. Thank you in advanced. Regards, Konstantinos

Ovirt remove network from hosted engine
by Abi Askushi 28 Jun '17

28 Jun '17

Hi all, When setting up hosted engine setup on top gluster with 3 nodes, I had gluster configured on a separate network interface, as recommended. When I tried later to upload ISO from engine to ISO domain, the engine was not able to upload it since the VM did not have access to the separate storage network. I then added the storage network interface to the hosted engine and ISO upload succeeded. 1st question: do I need to add the network interface to engine in order to upload ISOs? does there exist any alternate way? Then I proceeded to configure bonding for the storage domain, bonding 2 NICs at each server. When trying to set a custom bond of mode=6 (as recommended from gluster) I received a warning that mode0, 5 and 6 cannot be configured since the interface is used from VMs. I also understood that having the storage network assigned to VMs makes it a bridge which decreases performance of networking. When trying to remove the network interface from engine it cannot be done, since the engine is running. 2nd question: Is there a way I can remove the secondary storage network interface from the engine? Many thanx

oVirt split brain resolution

iSCSI storage domain and multipath when adding node
by Gianluca Cecchi 27 Jun '17

27 Jun '17

Hello, my configuration is what described here: http://lists.ovirt.org/pipermail/users/2017-March/080992.html So I'm using iSCSI multipath and not bonding can anyone reproduce? Initial situation is only one node configured and active with some VMS I go and configure a second node; it tries to activate but networks are not all already mapped and so gies to non operational. I setup all networks and activate the node It happens that: - on the first node where I currently have 2 iSCSI connections and 2multipath lines (with p1p1.100 and p1p2) it is instantiated a new iSCSI SID using interface "default" and in multipath -l output I see now 3 lines - on the newly added node I only see 1 iSCSI SID using interface default My way to solve the situation was to go inside iscsi multipath section do nothing but save the same config brutally on first node iscsiadm -m session -u --> all iscsi sessions are closed after a while I see again the original 2 connections recovered, with correct interface names used - on second node iscsiadm -m session -u --> the only session is cloed nothing happens if I set to maintenance the node and then activate the node --> the 2 correct iscsi sessions are activated... Thanks Gianluca

Re: [ovirt-users] oVirt Live USB3 question
by Lev Veyde 27 Jun '17

27 Jun '17

Hi Michael, I'm glad that I could help. Yes, while USB3 has an impressive interface (and thus potential) speed of up to 5 gbps (or over 600 MB/sec) the actual hardware normally provides speeds which for basic DOKs are even under USB 2.0 spec. in most cases (under 60 MB/sec.). However, as I also mentioned, it will only affect the time it takes to load, and from my experience with any decent DOK it's quite OK, you don't even have to invest into ultra-expensive and ultra-fast one, especially if you don't plan to "re-burn" the DOK very often.

Access VM Console on a Smart Phone with User Permission
by Jerome Roque 27 Jun '17

27 Jun '17

Good day oVirt Users, I need some little help. I have a KVM and used oVirt for the management of VMs. What I want is that my client will log on to their account and access their virtual machine using their Smart phone. I tried to install mOvirt and yes can connect to the console of my machine, but it is only accessible for admin console. Tried to use web console, it downloaded console.vv but can't open it. By any chance could make this thing possible? Thank you, Jerome
