How to migrate un-migratable VMs?
by Nicolas Ecarnot 18 May '16

18 May '16

Hi, Some VMs are doing high guest-memory writes (mainly files and mail servers, but not only), so migrations are reproductively failing. I found some info here : https://bugzilla.redhat.com/show_bug.cgi?id=919201 that confirm what I was fearing. This BZ is aging from dinosaurs times, so I was wondering now we're in the 3.6.x age and 4.x coming, are there advices one may give to migrate those verbose VMs? I guess increasing the allowed page memory is not a correct answer as it will fill as before. Any thoughts? -- Nicolas ECARNOT

Do you use ovirt-engine-reports?
by Yedidyah Bar David 18 May '16

18 May '16

Hi all, We are considering dropping ovirt-engine-reports in 4.0. Some of its functionality will be added in a new feature called "Dashboards", see [1]. Do you use Reports? How important it is to your setup? [1] https://bugzilla.redhat.com/1324860 Best regards, -- Didi

IsolatedNetworks
by Winfried de Heiden 17 May '16

17 May '16

Hi All, As described on http://old.ovirt.org/Features/IsolatedNetworks, Isolated networks in one of proposed features of oVirt 4.0: "The current host networking api (up to ovirt-engine-3.6) requires a network to be configured on top of a network interface. In order to configure a local network on the host the user had to create a dummy interface to which the network was attached. The Isolated Networks feature aimed to configure a local host on the network which isn't connected to any network interface and allows vms which are connected to it to communicate with each other. Isolated Networks will be limited to VM networks only and only MTU should be relevant in that network definition for the created isolated network." Hence, I should be able to create a host-only network with an underlaying NIC; sounds nice for my @home Cloud... However, runing oVirt 4.0 it is still complaining a NIC is misssing. I might have configured something wrong. How to set create an isolated network? Is there already any documentation? Kind regards, Winny

VMs seems to be slow, while snapshot delete is happening
by SATHEESARAN 17 May '16

17 May '16

Hi All, I have created a VM with 60GB of disk space. I have started I/O inside the VM, after sometime when the disk was 4GB full, I took a snapshot of the disk from UI. I/O kept continuing and the new image file ( overlay file ) was 15GB in size. Now I deleted the snapshot. I think this would initiate block-merges. During this time, my I/O was were slower, till the snapshot delete is completed. Its not very slow, but slow. Is this a known behavior ? Advance thanks, Satheesaran S

Re: [ovirt-users] Adding another host to my cluster
by Charles Tassell 16 May '16

Hey Gervais, Try enabling NetworkManager and firewalld before doing the hosted-engine --deploy. I have run into problems with oVirt trying to perform tasks on hosts where firewalld is disabled, so maybe you are running into a similar problem. Also, I think the setup script will disable NetworkManager if it needs to. I know I didn't manually disable it on any of the boxes I installed on.

USB
by Brett I. Holcomb 16 May '16

16 May '16

How do I get a VM to see USB devices? If I understand it correctly I have to go to Edit VM -> Console and enable USB native. I have the console options set to use usb. However, I'm finding conflicting information. Supposedly libvirt will allow sharing of a USB device over a network but to start with I'd be happy just being able to connect a usb device to the host and having it detected. I have some programmable devices I'd like to program in Linux using my VM. Has anyone uses usbip and if so how well does it work?
