I''m going to set up a PVM on xen-3.3.1 debian-amd64. I need advices about the best methods to install a fresh debian on it (i.e. how to choose the kernel for pvm) . I''ve installed xen from sources and only have one xen kernel in /boot which I''m using for dom0; should I use the same kernel for domUs? There is any problem on use vcpus=2; the other vm is an hvm running

Hello, I''m not subscribed to this list, but would like to ask a question. When I conduct a network speed test from the following location http://www.timewarnerla.com/speedtest/speedtest.asp with firewall started I get no more than 1 Mbps at best, while without one I get 4 Mbps. I have a RCA DCM325 cable modem from RoadRunner. I''m using Shorewall 2.2.0-Beta3. My OS is SuSe 9.1

(The list appears to have eaten my previous attempt to send this. Apologies if you receive multiple copies.) The attached patches allow you to use paravirtualised network and block interfaces from fully virtualised domains, based on Intel''s patches from a few months ago. These are significantly faster than the equivalent ioemu devices, sometimes by more than an order of magnitude.

Hi, this is my Linux Box ---------------------------- LAN 1 -----|--eth1 <---br1--->eth0.1 | | \ | | eth0--|----- 802.1q tagged 1 Mbps link | / | LAN 2 -----|--eth2 <---br2--->eth0.2 | ---------------------------- I have to bridge the 2 lans

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

Hi All, I have gone through threads related to throughput issue in this list. Found few similar issue, but could not get the solution. So looking for some advice from group. I am trying to use the samba to access a USB disk connected to our evaluation board which has xtensa core running at 400 MHz. Samba 3.5.x is running on the board. We are getting below throughput as tested with the

Hi, I have XEN 3.3 on Centos 5.4, my network interface have link 1 Gbps I want improve speed of network interface on virtual machine, from 100Mbps to 1Gpbs. Somebody have link that show do this ?

Hello, I use a script network-multi vlan and network-bridge-vlan for multiple VLANs in domu. Several domu uses the bridge vlanbr30. Need to dom0 as was in this vlan''e. How? I tried to put a bridge interface ip, but with him until the rest domu in vlanbr30 not get through. How to understand the need to create a virtual interface (vifx.y) and add it to the bridge vlanbr30. How?

I am using a 2.6.35 domU guest on a 2.6.32 dom0 and a 4.0.1 Xen hypervisor. Using netperf with UDP_RR I get 1819 and 622 transaction per second for domU and dom0 respectively, but in UDP_STREAM test domU is showing a better throughput for all packet sizes (on average around 3Mbps better, on a 10/100 network with around 96Mbps average native throuput). Is it normal or I am missing something?

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

Similar to another thread that was posted recently (archive: https://groups.google.com/forum/#!topic/linux.samba/sRvmCb25U_s) I'm trying to get multichannel working with a virtual Linux server running version 4.4.5.

Background - I am having an issue with occassional pauses when streaming high-bitrate media across my home network to my smart TV. I *suspect* that the root cause is the (incredibly lame) 100 Mbps Ethernet interface in the TV. In order to confirm that the peak bitrate really does max out the 100 Mbps connection, I'd like to monitor the communication between my NAS and the TV. The two

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!

## QUESTION I am sharing a 120GB folder with lots of files via Samba on a LAN (1Gbps connection). 1) Doing an `ls -lR` on the server (on this folder) takes ~32 seconds, compared with **72 minutes** on the client. Is this difference in performance expected (due to network and protocol overhead)? 2) While the client is executing an `ls -lR`, one smbd process on the server uses about 30-40% of a

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

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.

Hi Is there anyone who has successfully resolved the low throughput problem in Guest communication. I am using Xen3.4.1 with PV os kernel 2.6.30-rc6-tip On fedora11. While running netperf benchmark on guests throughput results are very low DomU to DomU    0.29 Mbps Why is it so? What would be the problem. Is there any issue with fc11 platform?

FYI for anyone using the dual ethernet ports on a Grandstream BT102. I'm using a BT102 connected to an HP2524 10/100 switch, which has an asterisk box connected directly to it. No VLANs defined or in use. Measured bandwidth: PC -> HP Switch -> Asterisk : actual throughput measured at 94.1 mbps. PC -> BT102 -> HP Switch -> Asterisk : actual measured at 8.86 mbps. The
