need to load uhci_hcd with acpi=off
Dear all, I have running a DOM-0 on debian squeeze with the most recent kernel: Linux 2.6.32-5-xen-amd64 #1 SMP On 30% of all reboots the system hangs and only a reset helps. acpi=off as an additional kernel parameter solves this problem, but the usb keyboard of the installed ip-kvm is not found then. with acpi=off Ican find a lot stuff like: [ 7.098747] uhci_hcd 0000:00:1d.2: UHCI Host

Bug#571634: bridge loosing connection
Hi, I'm not sure but I think I suffer under the same problem with a bit different setup with squeeze testing and xen 4.0rc5. In fact I'm using bridges in the dom0 and the connections to the domU get lost sporadically. In don't see where's a solution to the problem... Is it now a bug? When it's an iptables bug, where's the corresponding bug in the iptables bugtracker

Infinite loop shutting down xendomains
Pardon me for a long detailed post but this looks pretty serious. The bottom line is that, when I attempt to shut down or reboot my simple xen-2.0.7 server running FC3 with two domUs, shutting down xendomains appears to send python into an infinite loop. This may be due to a serious misconfiguration on my part but it is certainly a big problem. If we shutdown the domUs manually first, the

Problems with PCI pass-through
Hello! I'm having problems getting PCI pass-through to work. This is on a AMD64 system, paravirtualized with xen-hypervisor-4.0-amd64 4.0.0-1~experimental.1, dom0: linux-image-2.6.32-5-xen-amd64 2.6.32-12. From IRC, earlier today: <tschwinge> waldi: Aren't the Debian xen domU-capable kernels supposed to contain the PCI frontend (needed for PCI pass-through)? I'm getting:

Missing packets on Dom0 when sniffing bridge with wireshark/tethreal
Hi, I have a Centos5 machine running xen 3.0.3-41 with two NICs each on its own subnet: 192.168.1.x and 192.168.0.x. All DomUs can talk to each other OK through two xen bridges. There are 3 DomUs: Dom0, Dom1 and Dom2 The scenario: I''m trying to capture packets on Dom2 on 192.168.0.x from external devices that are sending SIP stuff to Dom1, but fail to capture any packets. I

Bug#659642: xen-hypervisor-4.0-amd64: outl segfaults when restoring monitor from sleep with DPMS
Package: xen-hypervisor-4.0-amd64 Version: 4.0.1-4 Severity: normal Tags: squeeze When the monitor is being restored from power saving mode via DPMS, X will lock up/restart. This only occurs when running Xen hypervisor. Running just 2.6.32-5 -xen-amd64 doesn't produce this effect. Note that both 2.6.32-5-xen-amd64 and 2.6.32-5-xen-amd64 with Xen 4.0.1 are running with nopat (to workaround

Doubled up RAM to 32 GB - now how to speed up a LAPP server?
Dear CentOS users, I run a small Facebook game at a CentOS 6.3 machine with PostgreSQL 8.4.3 + few PHP scripts + 1 Perl daemon and even though the server worked ok, I've suggested my users to double up the RAM to 32 GB and they have collected money for that. Now my problem is that I don't know, which knob to turn and how to really use the additional memory. Below is my top output at the

[BUG] Problem Booting Xen 4.0.1 on 2.6.32.26/27
Hello, I''m attempting to boot Xen 4.0.1 on a SuperMicro H8DGi-F motherboard and having not much luck. I can boot the 2.6.32.26 (or .27) kernels alone, but when I add Xen into the mix, I get consistent boot failure. I''ve tried Xen 4.0.1-release, 4.0.2-rc1-pre and 4.0.2-rc2-pre, all get the same failure. xen/next-2.6.37 works and boots great, but since netback isn''t

Debian Squeeze hangs with kernel 2.6.32-5-xen-686
Hi all! After upgrading to Squeeze, I am watching a Xen VMHost that after a while it hangs. This did not happen when I was using Xen with Debian Lenny (in this case as with Squeeze, the Xen components are from Debian repositories). In each case I connected a keyboard and monitor to the computer and the screen remained black without answering any key. This problem seems to also affect domUs,

Hard I/O lockup with EL6
I'm trying to figure out why 2 machines have a "hard I/O lock" on the HDD when running EL6. I have 4 identical machines, all were stable with EL5. 2 work great with EL6, 2 do not. I've checked momtherboard BIOS versions and settings, SAS controller BIOS versions and settings, they are the same between the working and non- working systems. When booting a non-working system,

Promiscuous mode
Hi Everyone, In order to prevent DomU from entering promiscuous mode, is it just a matter of adding these 2 rules when the vif is created? # Accept packets leaving the bridge going to the domU only if # the destination IP for that packet matches an authorized IPv4 # address for that domU. iptables -A FORWARD -m physdev --physdev-out vif1.0 \ --destination 216.146.46.43 -j ACCEPT

[SPAM] Xen bridge network issue
Hi, I have taken the long and winding road and indeed it lead me to your door. I need your help, please. My Xen includes 2 guests. Xen itself (10.2.0.52) gets free access to the outside world and to its guests. Both guests however (10.2.0.54/10.2.0.55) see each other but stay under house arrest! Not a single ping manages to go past the bridge (xenbr0) and get an answer from the default gateway

DOMU loses outside connection
When I start xen dom0 I get that same dhcp address for eth0 and for xen-br0, dom0 can talk to the world. If I start each of my 3 domU''s mannually, each guest gets a xen-br0 vif with a dhcp address and all 3 can talk to the outside world and each other (my "flat network"). What I want is a tiered network with the first domU acting as a firewall with 3 nics vif = [

No connection in DomUs with network-route
Hi, I would like to know if somebody can point me out how to configure several DomUs in a private LAN (for example 192.168.100.0/24) and one DomU with two interfaces (one - 192.168.100.0/24 and two - internet). So far I have enabled in xend-config.sxp: (network-script network-route) (vif-script vif-route) My config files have: /mnt/VM/1.cfg:vif = [''ip=192.168.1.3'']
