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

Hi folks, i have a problem to boot an Ubuntu CD in a hvm-enabled machine. I get a black screen when connecting via vnc to the virtual machine. When i change the line cdrom= to some other CD (grml Live CD, Windows CD, other ones) it runs fine. But any Ubuntu CD (kubuntu alternative, ubuntu server, ubuntu desktop) i get the mentioned error. I tried using sdl (no window opens) and with

Hi, As a previous thread in http://lists.xensource.com/archives/html/xen-users/2006-06/msg01111.html tells, it should be possible tun run hvm domains with a physical disk. There where other threads about this, but no solution for my current problem. When I try to use a disk defined as disk = [ ''phy:data/faitest-client-generic-hvm-disk,ioemu:hda,w''] (The device is a lvm

Most of them bases on latestest Qemu. The modifications are the below: Adding logic in ne2000_update_irq() avoids exceptional logic. Another modification is the ne2000_can_receive(), "if (index < boundary)" -> "if (index <= boundary)". Others based on lastest Qemu. But the latest Qemu adds new features, which not been added in the patch. The qemu uses polling

All, We are facing some issues bringing up a DomVT on Xen x86_64(changeset 9267). We created a disk image with dd 8 G in size. We then booted an associated Dom-VT with a CD-ROM and did net-install of the sles-9 OS. This completes successfully. Then, when the system is brought around for a reboot (having changed the boot option from cdrom to disk), the system hangs after the line

Greetings xen gurus... I''m working with xen-3.0-testing downloaded on July 3, 2006. I have configured an hvm domain and want to use vif-route and network-route to configure the communication. The domU starts up fine. I was able to complete the installation of the OS (RHES3) and can restart the domain repeatedly. However, I cannot ping the network interface from dom0 using the

Hello, I''m trying to get my first HVM domU installed (another Debian domU is already working under the same dom0). I intend to install the guest OS from a bootable CD-ROM. But when I create the new HVM domU with ''xm create xp1-cd.cfg'' , I don''t get the expected installation-window and find this in /var/log/xen/qemu-dm.6575.log: domid: 6 qemu: the number

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

I have a self built system using an Intel D 920 processor and a MB that supports VT. I''m able to run HVM domains fine, but have trouble getting multiple VCPUs for these domains. Here is an example of one of my configs. # -*- mode: python; -*- #============================================================================ # Python configuration setup for ''xm create''. #

As you know, HVM save/restore broke recently because restored config miss guest memsize that used by xc_hvm_restore to locate some pfn. After discussion, we decided to remove the pfn deduction logic from restore side by adding a general memory layout. I have a patch for it. But then qemu broke, because it also require the memsize to locate the share page. We can''t use the previous

I have used 3Com 3c509 nic width bnc coax. I have experienced that these cards used width FreeBSD and Samba is unusable due to speed. I tried to change the 3com card with a NE2000 compatible card, and there was a major change in speed. Has anyone else experienced such problem. Asgeir Stangeland

Hi all, I now have Xen running on Intel Core2 duo system, and am running a HVM domU with Microsoft Windows XP Home Edition, cold-installed from distribution CD. Problem is, Windows can''t get to the network. My dom0 ifconfig looks correct, as far as I can tell. I have a DHCP server on my local network, but the Windows XP domU claims to be unable to find DHCP. I''ve also tried
