VMs import over slow 1gig interface instead of fast 10gig interface?
Ok, so I want to try and more thoroughly explain my situation. I want to better understand what is happening, and if there is a way to force import over the faster connection. Today I have two Ovirt environments, one on 4.1 and one on 4.2, on the new environment we have migrated to new VLANs for Management and Data. The export domain is a NFS domain hosted on a Trunas device that has an ip address of X.X.12.100. Our host has multiple Ethernet connections, one Bonded 20Gigabit interface. That is where we have the ovirtmgmt profile. And a secondary 1 Gigabit interface that we call our VLAN12 profile or server VLAN. *The problem.... *When importing a VM from the export domain, the import is happening over the 1Gigabit interface on the VLAN12 profile. Instead of the 20gigabit Bonded interface on VLAN 100. *My understanding.... *So I probably just misunderstand how this works, but here is what I thought should happen, in the *Setup Host Network* screen for this host I have the ovirtmgmt on VLAN100 with the bonded 20Gigabit interface performing the following. "*Management, Display, Migration, VM and Default Route*." Then I have the secondary 1 Gigabit interface just doing "*VM*" on VLAN12. What I thought should happen is that anything Migration related "*/Includes importing from export domain?/*" should happen on the Migration interface, which in my case is the ovritmgmt interface on VLAN100. I have also confirmed that I can ping from the VLAN100 ovirtmgmt interface to the storage on VLAN12. So there is connectivity from that interface to the storage. What I am trying to figure out is there a way to force it to do imports over the 20Gigabit interface that resides on VLAN100 instead of the slower VLAN12 interface, that is just there for general VM connectivity. Thank you for any advice or guidance on this matter. -- Jacob Green Systems Admin American Alloy Steel

Importing vms from export domain is a storage operation, and it is nor related to migration. Maybe Dan can explain why accessing storage is done on the wrong network. Nir

Can you share the ip addresses you have set on your host interfaces? I suspect that your VLAN12 interface has a X.X.12.Y address, sharing the same subnet as your NFS server. When a hypervisor connects to a storage server, it prefers using the same subnet. If you can move your NFS server to VLAN100, you can re-add it to the data ceneter using its new address. Then, hosts would use the X.X.100.Y address to connect to it. HTH, Dan.

Thanks for your reply Dan and Nir, we are looking at adding a tagged vlan 100 to our storage for this very purpose! I agree it will travel over the correct link once the storage is on that subnet. On 11/18/2018 03:46 AM, Dan Kenigsberg wrote:

You should take part in a contest for one of the best blogs on the web. I will recommend this site! http://www.ballgames.site
This makes choosing the best antivirus an increasingly important decision that should be taken in careful consideration. Viruses can take many forms, often infiltrating your system without any indication whatsoever. http://mcafeecomactivateretailcard.com http://wwwofficecomsetupproductkey.com http://nortoncomsetupproductkey.com
This is an awesome post. Really informative and creative content. These concept is a good way to enhance the knowledge. I like it and help me to development very well. Thank you for this brief explanation and very nice information. Well, got a good knowledge. http://wwwofficecomsetupkey.com http://nortoncomsetupretailcard.com http://mcafeecomactivateretailkeycard.com
