Xen+Munin+Monit?
Hi All, What is the best way to remotely monitor/administer a group of xen domUs across a network? We''re planning to deploy a few H/W servers with paravirtualized domUs. What are the best alternatives? What works and What doesn''t? Share your experiences. Cheers Rajan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Possible bug in Xen 4.2.1 when rebooting domU after save/restore
Hello, After saving and restoring a DomU (teste on the same server), doing a reboot to the newly restored domU will cause it to crash. This happens on PV and PVHVM domUs. I am using qemu upstream for the HVM guests, but I don''t really think it matters as long as PV guests behave the same. I want to confirm this if possible, before submitting a bug report and more details. I am using

cpu frequency scaling in domUs
Hi, I''ve recently installed xen-3.2.1 on my AMD Sempron(tm) machine. It runs gentoo 2.6.21 as dom0 and cpu frequency scaling works in dom0. But inside a domU, cpu frequency scaling is not working. By checking the boot log in domU I found that domU is unable to load the powernow driver: "powernow-k8: BIOS error - no PSB or ACPI _PSS objects" I wonder if it is possible to have

vCPUs and Weight/Caps
Hello Everyone, I am hoping I can get some help with how vCPUs work with weights and caps 1. If I have a domU with 2 vCPUs and a weight of 256, does the weight double (512) or is this 256 time slice across both vCPUs. If the weight does not double, how is it beneficial to have multiple vCPUs? 2. If the domU has 2vCPUs and a cap of 100% how does this work since 100% is a mex of one physical

xen domU ID and static routing
Hi, I use a EQ 4 dedicated root server by hetzner with ubuntu jaunty. I installed xen 3.3 with debian kernel and brought up 3 domUs. Now comes networking... Hetzner does not allow bridged networking so I have to use routed mode in xen. No Problem so far, but the Problem actually is: When I bring up a domU the routing table is created by the xen-script vif-routing. The network interface name

drifting clock in domUs
Hello, On a xenserver with several (39) domUs, we experience problems with the system clock of the domUs. The clock seems to drift away several seconds up to two minutes from the dom0 clock. We do have set independent_wallclock=0. According to the docs (i.e. http://wiki.xensource.com/xenwiki/InstallationNotes) that way domUs should use the dom0 clock, but apparently that''s not the case.

Problem with some win3k3 domUs since crash
Yesterday all of my xen servers went down hard and also lost connection to ocfs2. 95% of the domU''s came back up ok, but I do have problems with a few windows domUs. They seem to start ok, but them immediately lose connection to the network. If I have them on DHCP they are on long enough to get an address, then they lose connection. If I look at the properties of the NIC it says 1GB

Using Proxy ARP inside Xen DomUs
Hello list I''m considering moving shorewall to a xen domu and the using the Proxy ARP method (we use NAT today). Is it possible to have a Proxy ARP firewall inside a domu serving requests to other domus with public IP-addresses placed on separate hardware (not the hardware the domu with the firewall is on) ? I figure that there''s a problem since it''s different bridges

Bug#799122: xen-hypervisor-4.4-amd64: Networking of domUs stops working after a few minutes
Package: xen-hypervisor-4.4-amd64 Version: 4.4.1-9+deb8u1 Severity: important A few minutes after starting a domU, network access is no longer possible from and to it. This does not always happen and is not easily reproducible, but seems to occur in all newly started domUs from some point in time on. However, also restarting the dom0 does not necessarily prevent the problem. At the moment when

Cannot start xen domUs anymore, domUs hang on kernel startup, happens after a long dom0 uptime
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.

DomUs hidden behind Dom0 in the network?
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

about page cache architecture of the dom0 and domUs in xen platform
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?

domUs with iSCSI disks... connect in dom0 or domU?
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
