similar to: time synchronization of dom0 and domUs still not working?

Hi everybody! I know this is an ultraknown issue, but in my case i think it is going beyond. As you may guess my domUs clocks go faster or slower They come with the same OS (Centos 5 2.6.18-92.1.18.el5 ) but each of them have a different clock speed. Why? Dom0 does not syncronize domUs : So i watched out looking for any solution.... First attempt: /proc/sys/xen/independent_wallclock = 0

Hello! I've noticed this problem two times now.. last time I fixed it by rebooting the (centos 5.1 x86 32b) xen host/dom0. Symptoms: - Already running domUs (debian 2.6.18-6-xen-686 32b PAE) continue running and working OK - Cannot start new domUs (debian 2.6.18-6-xen-686).. kernel bootup just hangs before running initrd. Same domU with the exact same xen domU cfgfile worked earlier.

Hi list! Now when Fedora 10 is out, I thought of writing here what's needed to run Fedora 10 Xen domUs on CentOS 5 dom0. Fedora 10 does not have separate kernel-xen, but instead Xen domU support is included in the normal kernel-PAE.i686 and kernel.x86_64 (based on the pv_ops Xen support included in the mainline/vanilla Linux kernels). RHEL 5.3 beta (and final obviously too) includes

Hello all, I'm addressing the mailing list following the suggestion of gwd on #centos-virt @freenode IRC. The subject says most of it. Here are the details : - Was running 4.4.x and configured such that /etc/xen/auto domUs would be saved/restored on dom0 shutdown/bootup. - Installation was based on "centos-release-xen" such that "yum upgrade" brough Xen to 4.6.1. After

I have a CentOS 5.1 dom0 running on a machine with two cores and 4gb of memory. It runs three 4.6 domUs and one 5.1 domU. Just out of the blue the other night all the 4.6 domUs crashed, but the dom0 stayed up. I ran xm console (domU-name) and got the Oops information below. I didn't get anything from the 5.1 domU. I think it had been rebooted a few days before and hadn't come up

Hello. I can't install 5.3 domUs in 5.3 dom0 with the very same /etc/xen/domU.cfg and remote domU.ks that I've used in Centos 5.1. The only I've changed is Centos version (including new 5.3 xen kernel and initrd images). Results are that anaconda can't assing networki configuration to network interface (probably because of not seeing it) and such error messages in xend.log:

Sorry for the top post, blackberry. Well I like to be able to install my machines in the xenstore with 'xm new' and then manage them from there, but virt-install and virsh are useful too, so I just use CentOS base then replace their xen with the one from xen.org keeping libvirt and now I have the best of both worlds. The commercial one isn't without gripes too. Like I wish they had

Hi, I encounter a problem that has puzzled me for a long time.On a Xen virtualization platform, some VMs ,whose virtual disks are image files ,are running in DomUs.Under this situation ,does the Dom0 cache the pages from the VMs?Does the filesystem in Dom0 see the VMs as general processes?

Hello folks, I have a Xen server running on Centos 6.2 with 3.6.6-1.el6xen.x86_64 as the Dom0 kernel, and i have dedicted 2 CPUs and 4G ram for the Dom0.I have close to 4-5 Virtual machines running on the Xen server. The problem is that for some reason,carrying outany CPU/Disk intensive task on the Dom0 seems to be affecting the DomUs adversly.For ex.i noticed that my Domus become extremly

centos-virt, I'm trying to create/install domU guests all in "one" step, following Daniel's wiki page (I've found these pages really helpful, BTW): http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU I have a few questions about this process: (1) How would it be modified (w/respect to defining the disk in the domain configuration file) to use a disk layout where dom0

I have a xen 3.0.2 running on a 733 MHz server, 1 GB RAM. It has two domU domains. dom0 has 512 MB, domUs have 256 MB each. Whenever load average on dom0 is above 1-2 (for example, compressing 200 MB file), I can''t reach any domU domain. Ping replies to domUs take very long time (it''s on LAN), and there are packet losses: 64 bytes from 192.168.11.61: icmp_seq=7 ttl=64

Hello, I am trying to set up a PVM (a the moment Ubuntu as guest and Ubuntu server as Dom0). The main issue is that the DomUs can''t get direct net access, because the access is restricted by a DHCP server that also functions as proxy to the outside of the network. The server controls the MAC address and only http is allowed as outgoing connection. So the domUs shouldn''t appear

Using a default xen3.0.1 setup for dom0(rhel4 distro) and domUs (gentoo, rhel4, centos4.2 distros, ttylinux) with the domUs all having dhcp turned on, is there an easy way to tell from within the dom0 what ip addresses were assigned to the domUs after bootup?

Hello, I have a live migration problem on my setup. Migrated DomUs hang, but continue as normal when migrated back. Both nodes are i386 Debian Squeeze dom0 (xen 4.0.1 + pvops0 2.6.32-5-xen-686) Node A is a 32bits 2.4 Ghz Pentium4, node B is a 32bits 2.0 Ghz Celeron. DomUs are Debian Squeeze (2.6.32-5-xen-686 >= 2.6.32-22 or 2.6.32-5-686-bigmem >= 2.6.32-22) and Ubuntu Maverick

Hi List, I don''t know if this is something that is a simple matter of opinion or if there are strong reasons to take one route or the other. I have dom0 nodes with dedicated bond interfaces that connect to a storage traffic-only VLAN. Currently I have a few domUs running that have large-ish volumes on the iSCSI SAN, and to present the volumes I''m connecting the dom0s to the

Hello, I''m using my dom0 on a RHLE 4.4 with xen 3.0.4-1. My domUs work on the same O/S, and any virtual disk is composed by 5 files : disk = [

I would like to thank you for all your xen support. There is now 1 week that I''m trying to find a way to get domus memory stats on CentOS using xen 3.0.3, I also tried with xen 3.4.4. I compiled the last libvirt from source, I heard that some libvirt api functions has been disabled by rhel developer because of a flaw, I readed that they had patched the xen driver in the past before they
