Ovirt remove network from hosted engine

by Abi Askushi

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

iSCSI storage domain and multipath when adding node

by Gianluca Cecchi

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

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

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
