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

Good day. I''m pretty curious, how they work with netinst (debian, suse, ubuntu, centos)... As I understand, at first start they downloads xen-aware kernel and netinst initrd from repository (with one user must point with other-config:install-repository)... But how they do it? I means, this some kind of script, some kind of variables... Really, I''d like to do few more

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:

Oh yes you can run XEN on VB. I am running the following config: ========= GUEST ========= [root@xenserver ~]# cat /etc/issue Citrix XenCloudPlatform Host 0.1.1-25823p [root@xenserver ~]# uname -a Linux xenserver 2.6.27.42-0.1.1.xs0.1.1.737.1065xen #1 SMP Fri Jan 15 16:20:16 EST 2010 i686 athlon i386 GNU/Linux ======== HOST ======== OS Name: Microsoft Windows 7 Ultimate OS

Hello everyone. I have the following problem that could help would appreciate. 1) Environment: HOST 1: xen-hypervisor-3.2-1-amd64 with all VM in LVM disk. HOST 2: XCP 0.5 2) The VM that I wish migrate is a domU in XEN and is debian lenny over LVM: ................................................................................................... # Configuration file for the Xen instance

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

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. 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

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, I am writing a small doc for people new to Xen. to be able to compile Xen from sources on Ubuntu. Please suggest some improvements for this how to or mistakes that you can point out. There is a technique of virtualization known as Xen and a hypervisor known as Xen. Like you have Firefox,Open Office,VLC and other softwares on your computer similary there is a software known as Xen.

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!

Hi, Ive been using Xen2 for ages, and it great, but ive decided to go to Xen 3. Ive got it working, but I want to ask a couple of questions about it. 1. There no longer seems to be a seperate DomU and Dom0 built when I build from source. Is this the new policy? this would suit me, as I always used Xen0 kernels in my guest domains anyway. 2. Ive got me a vmx (vanderpool / intel virtualization

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?
