Hi, In kubevirt, we discovered [1] that whenever e1000 is used for vNIC, link on the interface becomes ready several seconds after 'ifup' is executed, which for some buggy images like cirros may slow down boot process for up to 1 minute [2]. If we switch from e1000 to virtio, the link is brought up and ready almost immediately. For the record, I am using the following versions: - L0

Folks, I''m playing with maxbw on links (as opposed to flows) in Crossbow, and I have a couple of questions. First, the limts seem only advisory. The first example has the main host talking to a zone that has 172.16.17.100 configured on znic0. When there is no maxbw, the throughtput is as expected; when maxbw is 55M the throughput only drops to 76 Mbps: # netperf -H

Hello, I just grabbed http://bits.xensource.com/oss-xen/release/4.2.0-rc2/xen-4.2.0-rc2.tar.gz and tried to build it on Fedora 17 x86_64 host (gcc 4.7.0): make tools: .. make[5]: Entering directory `/root/xen/xen-4.2.0-rc2/tools/firmware'' make -C etherboot all make[6]: Entering directory `/root/xen/xen-4.2.0-rc2/tools/firmware/etherboot'' make -C ipxe/src bin/rtl8139.rom

Hi Folks, I have a snv_105 sxce host that I just can''t get to work as expected with crossbow + zones. My test host persephone, is a virtual machine running under VMware ESXi 3.5, with 2 virtual network cards (e1000), all on the same flat network/subnet. It started life just 2 days ago with a clean install of snv_95, and I LUed to 105 yesterday. To rule out any sharing issue, the first

Hello, While testing Fedora 16 Xen PVHVM guests I noticed the following problem: When starting F16 PVHVM guest I can see the vifX.0 and tapX.0 interfaces appear on dom0, but after the guest kernel (Linux 3.1.0) starts and loads PVHVM drivers the vif/tap interfaces disappear from dom0.. so the bridge in dom0 doesn''t have any vifs/taps connected to it anymore. Has anyone seen that

Have you experienced this? What's going on when this occurs? What do I need to do to keep it from occurring? Please advise. Thanks.

Is there any method to copy files from the guest to host? I use virbr networking where the host and the guest have different static IPs. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

The decision on which device type to use for disks, network and video cards on output used to be taken deep inside the converting functions. This is not always desirable. In particular, there are scenarios when this decision is made before the convertion takes place. E.g. in in-place mode, the decisions are taken and the output VM configuration is created outside of v2v tool. This patchset

xend uses rtl8139, and we want xl to be compatible with xm. Some older operating systems don''t have e1000 drivers, and we want widest compatibility rather than best performance (people who want good performance are best advised to use PV-on-HVM drivers). We''ll probably switch to a new default when switching to upstream qemu, in the Xen 4.2 release cycle. Signed-off-by: Ian

I opened a bug report earlier today but it doesn''t seem to have been added to the bugs database. I''m posting here in case one of the Crossbow developers might see it and confirm this behavior. Description Duplicate packets are generated whenever an aggregate is introduced into the network configuration. We''ve ruled out switch ports and physical bge interfaces as

For an office that is using VoIP phones to connect to Asterisk, is gigabit ethernet really necessary for the Asterisk box to connect to the switch? I know that I won't even approach the limits of 100 Mbps, but would gigabit help with latency / collisions when several calls are underway? The fact is, anything going outside the office will be over a data T1, so intuition tells me that 100

I am trying to connect two workstations (CentOS 3&4) directly using a straight through cat 5e cable with a crossover adapter on one of the ends. Both hosts have gigabit-capable ethernet card. According to lspci host 1 has: 03:0e.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01) and host 2 has: 05:00.0 Ethernet controller: Marvell Technology Group

Hi, Can you tell why my vnic built on top of an aggregation of 2 NICs of 1 Gbit/s doesn''t report a speed of 2 GBit/s ? [root at nazgul /]# dladm show-dev bge0 link: up speed: 1000Mb duplex: full bge1 link: down speed: 0Mb duplex: unknown bge2 link: down speed: 0Mb duplex: unknown bge3 link: down speed: 0Mb

Moving to public discussion... This was found with Xen hypervisor version supporting device unplugging and the domU kernel having net-/blkfront and pci platform built-in (or as module). The block device is defined as hda and the NIC type=ioemu (so theoretically guests without pv support would work, too). Since both drivers are present, the kernel tries to unplug the emulated devices and
