Comment on Trunks, Bonds, Bridges, and vLANs in Proxmox by bitbud

There is already an IP and gateway defined on the primary management interface. The additional bridge and IP assigned on the “storage vLAN” is to facilitate direct access (no routing) to the storage vLAN.

Since both IP’s are assigned to the host computer, there can be only one default gateway, in this case the management interface.

It is true, however, that the storage network is segmented and does not have any routes.

Hi, and thank you very much for this article. It matches exactly what I’m about to do in my home lab.

Nevertheles, I stil have one question. Talking about your storage/SAN network/vlan, you underline the fact that you don’t set up a gateway configuring IP on the dedicated bridge. Is there a special reason for that, put aside that I suppose that the storage network is a flat strictly isolated ?

If this is the case, I imagine that all machines connected to it must be multi-homed, with at least another leg plugged in, say a management VLAN, on which a gateway is configured (at least for updates)… Am I wrong ?

Thank you in advance for your answer

Comment on Updating Network Drivers on VMWare ESXi by bitbud

No issues here. In VMWare, what are you emulating for 1-disk controller, 2-network adapter. Also, what is the physical storage for the guest? Local, NFS, iSCSI?

Hi there!

I as well have a R710 server with ESXi 4.0 U1. I’m currently running 2 RHEL 5.5 64bit and I have high IOWait…

Did you ever experience this in your VM setup?

Thanks!

That’s a nice setup. I currently have 2 hosts with a shared iscsi SAN. I primarily use OpenVZ containers, because I haven’t been able to get KVM to perform as well. Any tricks you’d care to share? Also, aggregating munin interests me as well. Thanks.

I use KVM in production. My need is for full virtualization, which OpenVZ is not. The ability to run any OS, replacing the hardware install. To date, I have a four cluster Proxmox 1.4 system in place with 10+ iSCSI SANs all managed though the Proxmox storage system. When complete, the cluster should have 10 total Hosts. It is working quite well. There have been some gotcha’s along the way, mostly as I have gained understanding of the design of the Proxmox system.
