similar to: Arp not sent after live migrations on xen-unstable

Hi, I believe I can post this here. I have a domU ( Redhat 6) running in Paravirt mode. When I migrate this domU to another host, looks like the domU is freezing in the other host. When I take it back to original host ,it starts to run normally and this is what can see in dmesg of domU : suspending xenstore... trying to map vcpu_info 0 at ffff88000434b020, mfn b67660, offset 32 cpu 0 using

I am using Xen 3.1.0 in centos 5.4 I have one VM consuming 100% cpu  and all other VM (linux) become very slow (no ssh and vnc access). I could access host via ssh but not VM. host cpu is about 95% idle using dstat. Pls advise how to avoid this. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi All I Just installed XCP 0.5 and It is really cool products! I want to install it on 10 Strong machine I have in my system, but I wanted to know if there is any tool that can control all of them? There is Convirture and ovirt, http://virt-manager.et.redhat.com/ and http://www.openxenmanager.com/ eucalyptus? and opennebula? Can Some One recommend about a good tools for this? Thanks

Good day. We trying to test XCP cloud under some product-like load (4 hosts, each with 24Gb mem and 8 cores) But with just about 30-40 virtual machines I got an extreme load on dom0 on pool master host: LA is about 3.5-6, and most time are used by xapi and stunnel processes. It''s really bother me: what happens on higher load with few thousands of VMs with about 10-16 hosts in pool...

Good day. Is any way to boot PV VM without using pygrub? F.e. by supplying kernel image and initrd from dom0 filesystem? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hello! I''m investigate strange behaviour of vfb in paravirt domU (centos 5) VNC servers started after creating domain, but information in xenstore appears sometimes after 1-2 minutes after start. Why this happening? And how can i get VNC port immediate after creating of domU? Thank''s. -- Vasiliy G Tolstov <v.tolstov@selfip.ru> Selfip.Ru

We are utilizing the xen hypervisor on nexenta with ISCSI as our method of communication with the guests (currently ubuntu but could be moving to centos). Obviously jumbo packet support would be nice to have. The last time I see that on the xen roadmap http://wiki.xensource.com/xenwiki/XenRoadMap . Is there a canonical place that spells out if jumbo frames are now supported or still on the

hello guys, i was wondering where and if i can find the xen kernel headers for the latest stable XCP (0.5) i need these because i have to compile a kernel module. Thanks!

Hi, all I''m totally new to XCP, so maybe i misunderstood the documentation. I tried to create Debian Squeeze (64-bit) and Ubuntu 10.04 from templates and install them from network installation. For Debian Squeeze (64-bit), I did the followings: 1. First ssh login into XCP host 2. xe vm-install template="Debian Squeeze (64-bit)" new-name-label=lenny-64-netinstall

Hi Folks: I am a NOOB and need some help and/or advice about debugging a domU VM boot problem in XCP 1.0 beta. I am trying to get my first VM installed over the network using XCP 1.0 beta. I am able to get to the VNC boot window but the installation process fails after a few minutes with this error: Unable to retrieve http://10.45.2.1//tcc/os/CentOS-5.5-x86_64/images/stage2.img

I have two hosts as Xen Server named host A and host B in the same network. A VM is created on Host A. Host A and B have a shared storage using NFS. While doing migration from host A to host B, how can I see the memory pages being migrated. If I run a small continuous program on the VM residing on host A, will the migration complete first or the sript running will complete first? How can I see

Good day. Which ports are used by xapi? I suddenly found it using tcp/13993 and I''m slightly concern about possible collision between xapi and my own application, running on dom0 on XCP...

Good day. XCP 0.5 xe host-evacuate uuid=f9458b0b-5e35-4ee0-adcf-c8945a37868c You attempted an operation on a VM which requires a more recent version of the PV drivers. Please upgrade your PV drivers. vm: a84aaf23-8afe-2ccc-0299-83b9dfd08c35 But at really vm uuid with bad PV-drivers is 42e397c7-3d76-02c0-a1f9-c78d79cac6c6 and no uuid a84aaf23... present in pool.

Hello, I've created a routed network that forwards to a physical interface: <network> <name>default</name> <forward dev='eth0' mode='route'/> <mac address='52:54:00:f2:5b:4f'/> <ip address='192.168.100.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.100.10'

I think I wrote not very clearly. I say ''swap in domU will save in case lag or little mistake with balloon''. If course, there is no any kind of ballooning for dom0. Right now we running pretty much VMs for our cloud services and we use heavy memory management (it grabs and gives memory with lag less then second depends on usage in customers VM). And we have some statistics

As I understand concept of xenballooning, it allow to take memory from guest and return it to hypervisor. This allow to reduce amount of memory allocated to VM in realtime without rebooting VM. But how we can add more memory to guest VM in realtime, than was at boot time? Can we somehow make balloon inflated at start time? (F.e. VM starts with memory = 512Mb and balloon inflating to +512Mb).
