similar to: Number of xenbr''s limited to four on openSuSE 10.2 ?

Hello all, I have a Xen server with 6 network interfaces, I want a bridge on all of them. I use a personal network script like this : #!/bin/bash dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=0 netdev=eth0 bridge=xenbr0 "$dir/network-bridge" "$@" vifnum=1 netdev=eth1 bridge=xenbr1 "$dir/network-bridge" "$@"

I have a OpenSuse 10.3 with xen 3.1.0 running and it''s been running fine for a few months. This past weekend it suddenly started to act up and after some troubleshooting I can now say that it seems like the guests(domU) loose the outgoing network pipe, from the console I can see that the TX counter is stuck at the same value but it''s no errors. It behaves as if whatever I try to

Hi, I''m using Xen 3.0.3 on two servers with Debian Etch (amd64). These servers have 10 nics (2 onboard and 8 in two 4-port cards) so that every vm can have its own interface. This worked so far with the Xen Version from Etch with a wrapper script wich started 10 bridges at boot time. But now I''ve updated Xen on one of these server to Xen 3.2.0 from backports.org and now the

Hi, does somebody know, if there is any documentation available on how to set mac addresses on virtual bridges / virtual interfaces? Keeping track of every mac in the particular segments is really impractical.

Hi I''m testing around with xen 3.0 snapshot from last week. And i''m now having a problem with a xenbr which is based on a vlan if (dot1q). this is all in dom0 os: debian testing network: tg3 I can start the bridge based on my normal physical eth0 which is working without any problems. My clan without bridge is also working. I can start the bridge based on a vlan if with help

Hi, We have a storage server (HP DL360G5 + MSA20 (12 disks in RAID 6) on a SmartArray6400). 10 directories are exported through nfs to 10 clients (rsize=32768,wsize=32768,soft,intr,nosuid,proto=udp,vers=3). The server is apparently not doing much but... we have very high waiting IOs. dstat show very little activity, but high 'wai'... # dstat ----total-cpu-usage---- -dsk/total-

Hi, I've been using CentOS & Xen on a server that has 2 VM's configured. The default configuration includes one physical iface that is propagated (by a default bridge) to the VM's. Since I wanted to configure additional physical iface, define a new bridge and propagate it to the viface-s of the VM's, i configured the bridge/phys. iface and brought it up (here are

Hi All, We have a single Centos 5.11 server running a xen hypervisor that went down hard after an extended power outage this weekend. I'm mostly familiar for KVM as that is the majority of what our guests run under and have tried getting up to speed on xen bridging to no avail. The problem is that after the xen server spun back up, the previously defined xen bridges were lost. I've

I am experiencing poor network performance on Dom0. When i ping other hosts on the same LAN, packets are out of order, and they show response times ranging from < 1 ms to several seconds, and some packets get lost. For example, a typical ping result looks like this: 87 packets transmitted, 80 received, +3 errors, 8% packet loss, time 86038ms rtt min/avg/max/mdev =

Is there any real user for this vIRQ? I''m asking because, while debugging a problem that required to add some printk()s that could temporarily issue at a high rate, I ran into the situation that this extra output prevented guest/dom0 boot from making any progress. As I then realized this was due to the tasklet_schedule() called from inside the console handling code, which resulted in

Populate-on-demand: Check pages being returned by the balloon driver This patch series is the second result of my work last summer on decreasing fragmentation of superpages in a guests'' p2m when using populate-on-demand. This patch series is against 4.1; I''m posting it to get feedback on the viability of getting a ported version of this patch into 4.2. As with the previous

Hi @all, I tried to setup xen 3.3 on centos 5 Update 2. I used the following packages: http://bderzhavets.blogspot.com/2008/08/install-xen-3.html The server has 4 physical network interfaces and i want to use them all. eth0 => only for host (configured with static ip) eth1 => first vm (configured with static ip) eth2 => second vm (configured with static ip) eth3 => all other vm

Hi, I was hoping someone on this forums could help me out with a problem I was facing with Xen. When I compiled the kernel for Xen-3.1.3 using "make world"(I know this is an old version but I need to use it for some compatibility issues), the kernel was missing the Xen netloop module. There was no /kernel/drivers/xen/netback/netloop.ko in the newly compiled kernel. I think we would

Thanks to debugging information from Thomas Mieslinger, I have root-caused the failure of chain.c32 in Syslinux 3.85. I have put out Syslinux 3.86-pre1 and Syslinux 4.00-pre33 which fix the problem. I expect to release a Syslinux 3.86 relatively shortly (ideally in the next two weeks), with bug fixes only. I would like to figure out if there are other bug fixes we can get in in reasonable time,

Hello, I seem to be having some troubles regarding the latest 2.6.31.6 and 2.6.32.9 Xen dom0 pv_ops trees. Our platform: -Xen 3.4.3-rc3 (also tried 3.4.2 on 2.6.31.6 pv_ops dom0) -2.6.32.9 pv_ops dom0 kernel, perhaps a week old checkout from xen/stable git (can provide changeset if requested). -100+ domU''s, all PV. Ever since we switched to a pv_ops dom0 kernel (we were using 2.6.26

Today I found I can not ping some of my domU''s. I logged in to dom0, did a "xm list", all domU are there. Then I did a "ifconfig" and surprised to find some of vif''s disappeared! Like for example. "xm list" show dom13 is alive, but "brctl show" shows no vif13.0. If I "xm console 13", there''s some message: WARNING:

Hi, folks, Since I've gotten a total of one response in days on the HP forum, maybe the collective mind here has an answer.... As I've mentioned in other posts, we have an HP dl580 g5 that started throwing ECC errors. But wait, it's worse: memory is mirrored.... And the thing is fully populated with 32 DIMMs. I took my best guess, pulled the matching set of DIMMs, and took two

Hi Everyone, In my HVM guest''s config file, I have given my guest 3 interface. I have called them fw1, fw2 and fw3. I have joined each interface to a bridge on the Dom0. This does appear when I do a "brctl show". However, there are 3 other interfaces also added called tapx.0,tapx.1 and tapx.2 (Where x is the domain ID for the guest). Furthermore, I am only able to run

Hi, with reference to RH BZ#567540 [0], this patch makes the netloop module permanent (like netback is currently). It reverts parts of xen-unstable c/s 9019:271cb04a4f2b [1] [2] (though that has a typo: "__init clean_loopback", so it was probably changed later too). The patch fixes the problem of "rmmod netloop" hanging, resulting in blocked tasks and inability to shut down
