...ase it was not enough - swap will save guest VM from been OOMkilled. So I strongly supports for domU swap. -------- Original Message -------- Subject: Re: [Xen-users] Swap: create or not?

If your application needs that much more RAM you''ll be better off giving that VM more RAM instead. If your application doesn''t give a damn about me...

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

Good day. I found that XCP ignores VCPU-params (weight and cap) after VM live migration, as well, as those parameters ignored if changed on running VM. May I as someone with xcp cloud nearly check this bug? Thank you. -- wBR,George. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

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.

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...

Hello. OpenSSH has -D option to create socks proxy (take local traffic and send it from remote machine). But sometimes there is an opposite problem: to allow apps on remote machine send traffic from local machine (for example, to get access to intranet resources).

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

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

So i successfully upgraded my Debian vm''s to Debian 6 on XCP 1.0, but when i try to install a new clean one it always fails. Why is this? The VM won''t even start, while i used the Debian 6 squeeze template. Is this even possible?

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, 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.

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).

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:
