Hi! I am building a KVM cluster that needs VM live migration. My shared storage as well as the KVM hosts will be running CentOS. Because 10 Gbps Ethernet switches are very expensive at the moment I will connect the KVM hosts to the storage by cross-over cables and create private networks for each connection (10.0.0.0/30 and 10.0.0.4/30). The following diagram shows the topology Management

Dear Marius, In addition to that attached please find a screenshot from Proxmox on statistics. Do you know any ice cast servers that puts out more than 1 gbps for a longer period? Just curious whether anyone was able to go beyond 1 gbps for an extensive time. Thank you!

Hi Zsolt, looking at the metrics from Proxmox it doesn't look like anything breaks there. What about at the operating system level? Could there be some limits there? Have you checked corresponding kernel or system logs? Which OS/distribution are you using? Checked the logs there? If nothing screams there, maybe start looking at a load balancer and scale with several more VMs? -- Marius

Dear Marius, Our station is Megadanceradio in Hungary. Our status page for the master server is: http://45.67.158.93:8000/status.xsl For the slave: http://45.67.158.94:8000/status.xsl We are peaking at around 11.00 am and 13.00 pm in the afternoon. We have tested extensively the bandwith with speedtest. We tried with iperf but that did not finish for a long time so we stopped it. Currently

A quick Google search indicates that it might be a Proxmox limitation: https://forum.proxmox.com/threads/i-cant-exceed-1gb-of-internet-with-a-10gb-network-card.128710/ On Fri, Mar 15, 2024 at 12:24?PM Marius Flage <marius at flage.org> wrote: > Hi Zsolt, > > looking at the metrics from Proxmox it doesn't look like anything breaks > there.

I don't know if any such limitation exists, but maxing out just shy of 1Gbps sounds a bit more like an interface's line speed limited/set to 1Gbps somewhere in your production chain? You wrote that you have tested the bw - what did you use? Iperf? Speedtest?Maybe consider scaling with additional Icecast servers and use a load balancer in front? And then just scale accordingly? This sounds

Dear Icecast, We are operating a web radio on a 10 Gbps dedicated server line. The line bandwidth is tested and available. The web radio is hosted on a Proxmox virtual environment. We own the physical server itself and made sure to have allocated the sufficient amount of resources on the virtual machine. We found that no matter what we do overall upload cannot go over 1 gbps on 1 mount point. It

OK, it seems that the kernel I have (stock CentOS 4.7: 2.6.9-78.0.22.EL i686) seems to gronk the nVideo SATA controller in AHCI mode. It is NOT able to deal with the SATA DVD Burner I have. It is a "Sony Optiarc DVD Burner with LightScribe Black SATA Model AD-7241S-0B LightScribe Support". Is there some special magic I need to do? Here is the relevant bit from the boot up (SATA ports

Hi folks. I'm posting this to both the Fedora as well as the CentOS lists in hopes that somewhere, someone can help me figure out what's going on. I have a dual Xeon 3GHz server that's performing rather slow when it comes to disk activities. The machine is configured with a single 160 GiB OS drive (with CentOS 5.0) and 4x500 GiB drives setup in a RAID-5 configuration.

Maybe one of you has experienced something like this before. I have a host running CentOS5.3, x86_64 version with the standard qla2xxx driver. Both ports are recognized and show output in dmesg but they never find my storage device: qla2xxx 0000:07:00.1: LIP reset occured (f700). qla2xxx 0000:07:00.1: LIP occured (f700). qla2xxx 0000:07:00.1: LIP reset occured (f7f7). qla2xxx 0000:07:00.0: LOOP

On my machine I have SATA0: HD SATA1: HD these two drives are set as RAID1 SATA2: HD extra SATA3: DVD SATA4: external USB disk Snip from dmesg shows the ATAPI device being detected. ata3: SATA max UDMA/133 cmd 0x9e0 ctl 0xbe0 bmdma 0xe400 irq 10 ata4: SATA max UDMA/133 cmd 0x960 ctl 0xb60 bmdma 0xe408 irq 10 ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata3.00: ATAPI: PIONEER BD-ROM

First, I apologize if this message has been received multiple times. I''m having problems subscribing to this mailing list: Hi xen-users, I am trying to decide whether I should run a game server inside a Xen domain. My primary reason for wanting to virtualize is because I want to isolate this environment from the rest of my server. I really like the idea of isolating the game server

Hi all, as good? I try to install asterisk-1.2.14, zaptel-1.2.12,libpri-1.2.4,addons-1.2.5 , sounds-1.2.1 and wanpipe-2.3.4-3 and hwec-utils-beta4-2.3.4 But it is not compiling drivers of the Sangoma, why udev's for board in "/dev/zap"(1-31, channel,ctl,pseudo,timer) is not created. But when I install a board TE110P Digium, udev's is created and asterisk functions perfectly. : )

Hi guys, I'm yet to use 10 Gbps with CentOS, hence my question. I'm looking for a cheap (doh) adapter that won't cause me problems with CentOS. Any recommendations? Cheers Lucian -- Sent from the Delta quadrant using Borg technology! Nux! www.nux.ro
