The attached patch to the qemu emulation of the pcnet hardware fixes several problems. It will now only read and write a transmit or receive descriptor once. It will correctly handle transmitting frames with more than two fragments. It will discard oversize frames instead of corrupting memory. I have tested all the changes I have made and even seen an improvement in receive performance from

Hi all: I use Charito to test xen default network(pcnet), and ne2000 performance, to my surpise, the average throughput of the default is 40Mbps, but the average throughput of ne2000 is 18Mbps, how can this happen? Besides, I see from xen wiki that : "The default network card which QEMU uses in Vt-x is AMD PCnet-PCI II Ethernet Controller. (*file tools/ioemu/hw/pcnet.c*). The reason to

Has anyone gotten networking in an HVM domain to work with the emulated NE2000 rather than the emulated PCnet? I have Linux running in an HVM domain just fine with pcnet. If I change the config file to say ne2000=1, the tun0, vif0.1, and xenbr0 devices get created in dom0, the kernel in the HVM domain brings up eth0 OK (NE2000 support is built into the kernel), but I can''t get dom0 to

Hi friends. Searching for info about how to setup acp pcnet card on nut? Any info will be accepted, thanks!!!

syslinux-4.00-pre5-10-gdc10f7b locks up on qemu with pcnet card. The problem seems to be in pxe_idle_init().

Is this the right list for this question, or should I be elsewhere? I am trying to specify a network card "model type" of "pcnet" (to emulate vmware esxi's network card). No matter what I put for model type in my xml config file, it comes up as an Intel e1000. I ran "qemu-kvm -net nic,model=? /dev/null" and I got back a list of supported models including

Samba Masters: I have a couple of Windows NT machines (server and workstation) that are having difficulty accessing a Samba server (1.9.17p4). When I try to connect from the NT box to the Samba server I get the error message "Account unauthorized to login from this station." The NT machines are not configured to participate in a Windows NT domain (although I tried that to see if it

I used to be able to load printer drivers via "server properties". Now when I go in the printer drivers are listed and I can use the properties button but the Add/Remove buttons are greyed out.

This is virtualbox 4.1.18 from debian wheezy emulation a PCnet-Fast III Network Interface because the default emulated card from Intel does not support PXE in virtualbox.

Hi All, I am having a problem with Samba that seems to be a bug. I say this because I read the archives and they described a problem similar to mine and were told that it was a bug in older version of Samba and the latest version should have it fixed. I am running what is essentially a RH 7.3 on a 1.4GHz Athon with 1GB or RAM. I compiled Samba 2.2.5 in /opt/samba-2.2.5 and am using the following

Hello , I use Centos 5.4 , with the redhat version of xen . I need for some guest to change the hardware for the network . So in my xen config i add the model option in the vif line . When the guest boot , i had the right emulation , but after a reboot , the guest loose the configuration . Someone can confirm the bug in centos 5.5 ? Have someone a patch ? Extract of my config : builder

It seems it's not possible to monitor kvm virtual image network interfaces via SNMP. MRTG's cfgmaker says ### The following interface is commented out because: ### * has no ifSpeed property and other monitors are consistently reporting that vm's interfaces are exceeding traffic thresholds (even on lo ...). Which is no surprise if the threshold is zero. I found a hint on some

I'm running KVM on a standard Debian Lenny host, and I seem to be hitting the problem identified here: http://serverfault.com/questions/123566/is-anyone-using-kvm-in-production My symptom is that using rsync over SSH to transfer files into the guest gets slower and slower, and then grinds to a halt, and the machine becomes unreachable. It seems that I should be using the virtio driver,

Just to let people know what's going on: The embargo for XSA-135 lifted today at 1400 UTC. The embargoes for XSAs 134 and 136 lift tomorrow at 1200 UTC. XSA-135 only affects guests which have been assigned a PCNET emulated NIC, which is not the default; as such, it doesn't seem terribly urgent to push the fix today. So rather than push one fix today and another tomorrow, our plan is

Good morning, I installed on xen a windows XP and a Windows 2003 domU. Windows operating system does not know the real network card but it setup up an AMD pcnet card 10mbps. Is it possible to setup a full virtualized domU with a real network card ? I installed also windows on a trial xen enterprise and real network card seeems to work fine. What differences between xen and xen entrprise as far
