similar to: (strange idea) unfriendly migration

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

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

Hi, All I''m just new to this list, I''m started to dealing with OSS Xen to XCP migration earlier this week, seem the domUs installed via virt-install are function well, but domUs copied via dom0 are failed during bootup process, finally I realize if I could fix this on my OSS Xen will resolve all. Can I have any suggestion from you please ? *Details* *Source XenHost* OS:

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. I think, it is an error in

Hi All, Having an issue with xen-4.0-unstable where after completing a live migration, an arp is never sent out to update the switch with the new location of the mac address. Network is configured as per libvirt''s instructions with the xen network-script disabled and the bridge (xenbr0) always up.

Package: xcp-xapi Version: 1.3.2-6 Severity: normal Tags: upstream vbd plug to PV domain cause following error: The server failed to handle your request, due to an internal error. The given message may give details useful for debugging the problem. message: the device disappeared from xenstore (frontend (domid=4 | kind=vbd | devid=51760); backend (domid=0 | kind=vbd | devid=51760)) (same error

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

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

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

I''ve recently noticed that my windows crash dumps fail at around 40-50% under GPLPV. ''xm dmesg'' shows the following: (XEN) grant_table.c:350:d0 Iomem mapping not permitted ffffffffffffffff (domain 865) At first I thought that the cause was just a bug in my grant ref code but it just occurred to me that this could be happening when Windows tries to write out the

Hi there, Last night I was trying to start a HVM domU via stubdom-dm device model. Initially I did not receive any error to stdout when I did so with Xen-3.4.2. My Xen-3.4.2 installation works fine with qemu-dm (or regular HVM guests). The stubdom-dm guest I was trying to create did not really operate as I was unable to connect to the VNC console. The output of xm list showed the DomU was there,

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

Package: xcp-xapi Version: 1.3.2-6 Severity: normal Tags: upstream Normally (in 'iso-based' XCP) is possible to attach VDI to dom0. That operation usually looks like: xe vbd-create vdi-uuid=... vm-uuid=(dom0 uuid) device=N xe vbd-plug I done those steps in xcp-xapi and got success (no error), but no xvd* device found. Here operations log: # xe vbd-create

Hi all, Can Xen hypervisor modify HVM domU's Shadow page table, under the dom0's context, like trapped from dom0's hypercall? I think it have to call 2 functions at least: guest_walk_tables() and flush_tlb_all(). Can these 2 functions called in dom0's context? In my test, if hypervisor tries to modify HVM's shadow page table, it will bring down the whole system. I am not

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...

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!

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...

samuel, I have a try with HVM stubdomain on r17062, but failed to make on 32b platform. Attached patch can fix it, but don''t know if okay. After installation, I failed to start stubdom. So I created it manually and got following debug mesg(both HVMdomain and stubdom are created) Can you give some lights on following questions: 1. I use default vnclisten. Does it matter? 2. Seems qemu
