similar to: passing kernel arguments to domU kernel

Hi folks, I started testing the antispoof feature of xen stable (2.0.7). I am stuck with it. I have setup a standard bridged environment. I understood it like this: in domU config I set up the virtual NIC like vif = [ ''mac=ae:00:00:78:78:78, ip=192.168.0.100'' ] Then I configure /etc/network/interface of this domU to show the same IP address for eth0. After restarting

Dear all, I have set up one unprivileged Domain-1 with help of FedoraQuickStart and some help from you. Now I want to install some other OS to Domain-2. How can I install a different OS (say Redhat 7.3) onto a unprivileged domain? Do I have to copy all files from an existed installation to an image file?

Hi All, I have just started looking at the code for Xen so please bear with me. A domU Linux kernel running with independent_wallclock=1 seems to sync its time with dom0 after every "xm unpause" (obviously preceded by an "xm pause"). I don''t see where the xtime variable is being updated after an "xm unpause", i.e., domain_unpause_by_systemcontroller().

Hi all, where can I set the date in domU. ''ntpdate -u ...'' works but dosn''t set the date. date MMDDhhmm has also no effect. What can I do? -- cu Roland Kruggel  mailto: rk-liste@gmx.de System: Intel 3.2Ghz, Debian etch, 2.6.15, KDE 3.4 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Hello ! Just a quick question about time synchronization between xen dom0 and domUs... We''re running Xen 3.1 64-bit, with 32 and 64 bits linux guests. It''s up since 89 days and the domU''s time is around 5 minutes behind the dom0, which is updated via ntpdate... Any idea why it doesn''t sync the guests even that /proc/sys/xen/independent_wallclock is 0 ?

Hey, I have rather new installation of xen, dom0 is running ntpd and is perfectly in time. All domU''s are ~23s in future. Running ntpd on the domU''s seem to have no effect, /proc/sys/xen/independent_wallclock appears to have no effect. I''m running xen-unstable and 2.6.16-rc4 in AMD64 box. Any tip would be appricated. Thanks, -- ++ytti

I think it''s perfect the way it is. Run NTP in dom0, all the domU''s then have synchronized time. I can still set timezones on all of these boxes independantly. Timezone has nothing to do with NTP synchronization. Tim:> > yeah, i''m already doing that, I was just saying, it *seemed* > like they were getting their time from domain0, and weren''t >

Hi folks, I am trying to get antispoofing running on xen3 (based on Debian Sarge). This is what I have done to enable it: 1. I have compiled a dom0 kernel with CONFIG_NETFILTER_XT_MATCH_PHYSDEV=m 2. I made sure this module is loaded: lsmod gives xt_physdev (among others). 3a. I have changed the line "(network-script network-bridge)" to "(network-script network-bridge

Hi all, I am running Scientific Linux 5.1 (rhel 5.1 compatible) 64bit on a 2x4core system with 16 gb ram with 3 Scientific Linux 4.6 (rhel 4.6 compatible) guests an one Scientific Linux 5.1 guest. I do not run ntp on the guests but only on dom0. One specific Scientific Linux 4 domU always looses time synchronization with dom0. All the others SL4 and the SL5 domUs remain synchronized. There

I am running a Fedora 9 domU on CentOS 5.2 dom0, and it is quite unreliable. Every few days I have the following phenomenon: - many applications do not work at all (e. g. Nagios 3.05 stops checking, but the cgis work perfectly, the web server works as well) - system processes run into time outs (e. g. logging in via ssh runs into timeouts <<"connection reset by peer">>

Package: xen Severity: important Version: 4.0.1-1 The Xen documentation and Xen Debian wiki describes using independent_wallclock to sync domU clocks against the dom0 clock http://docs.vmd.citrix.com/XenServer/4.0.1/guest/ch04s06.html http://wiki.debian.org/Xen#Possible_problems_and_bugs-1 This sysctl appears to have gone away with squeeze, but the documentation is not updated Time drift is

Hi, I am facing problem in sync time within DomU with Dom0. After gone through mailing lists, I have set /proc/sys/xen/independent_wallclock to 0. But still DomU are not syncing their time :-S Machine using kernel-xen-2.6.19-1.2911.fc6 xen-3.0.3-3.fc6 xen-libs-3.0.3-3.fc6 Please advice to solve this weird problem, Thanks _______________________________________________ Xen-users mailing list

Hello, I did a security-update for lenny a kernel on my dom0. And I rebooted one of the domU's (not sure if that's related). Now I have a problem with the time in the domU's. The time does not change anymore. The time is different in the different domU's. I don't use an independent_wallclock, so the time should be the same on the dom0 and the domU's. In the dom0 there is

Hi folks, I have set up a cluster on CentOS 5.2 using /etc/cluster/cluster.conf - and it works fine. It's only purpose is to switch a virtual IP between two routers. Now the service is running, I can ping the virtual IP from outside - but this virtual IP is not bound to any interface. How does this work? Can I force the cluster to bind it to a certain interface? I need this because the

Hi folks, I hope this is the right place to ask - if not I can switch to the CentOS mailing list. I am running GITCOs 3.4.3 hypervisor with original RHEL5.5/CentOS5.5 kernels in dom0 and domU. I have phenonema I want to get rid of (like time running wild - really wild). So I am looking for a way to compile a kernel with all CentOS refinements/backports/additions and xen 3.4.3. I have

I don''t want my dom0 to update the clock in my HVM domU. I''ve already disabled network-based time synchronization inside the HVM. I''ve tried setting /proc/sys/xen/independent_wallclock=1 and then restarting xend, but the guest still gets the correct time. Any ideas on how to accomplish this?

Hello you all out there Does anybody know the definite guide to create a dummy ethernet device? So, what I want to have is an ethernet device, without a physical link, or so called a dummy device. My goal is to have apache with mod_proxy and balancer running on peth0 in dom0. Apache is spreading my connection to the backend domU''s, where the webservices are running. The connection

Hi all, I'm having issue with my Centos 5.1 /Xen installation. I'm having 2 dom0 running 2.6.18-53.1.4.el5xen (x86_64). These two dom0 are connected to a SAN. These two dom0 hosts multiple domU like Centos 4.5 (2.6.9-55.0.9.ELxenU) and Centos 5.1 (2.6.18-53.1.4.el5xen). These two dom0 run ntpd to synchronize dom0 time. When i start a virtual machine on the first dom0 all seems good, the
