Hi, I run a small company and I would like to virtualise our setup. My internet provider offers a cloud server running CentOS. The server is managed by vmware software, they haven't been able to tell me exactly what. I wanted to know is it possible to virtualise such a setup, and Have CentOS running as the virtual OS that every client sees. Is there a solution similar to vmware view + client

Hello all, I have already use xen for about a year. I use recently released Opensuse 11.3 (use Xen 4.0) for my experiment. I want to run 3D test in HVM(windows xp), so I want to use VGA passthrough technology. But there is something not work properly. I google a lot of time, it says, I/O virtualisation should be enabled, but I can solve it. I run "xm dmesg" command, in the output, there is "(Xen) I/O virtualisation disabled", what I should do to enable I/O virtualisation. Can anyone help me? motherboard verison is intel DG965RY. Thank you! 2010-08-21 Di...

...lled it's impossible to migrate a VM from node to node or back it up without shutting the VM down first, which is less than useful. So I have two questions: 1) Does anyone know if there is a version of the PCS6 Tools built against glibc 2.3.4 available anywhere? 2) Is there an alternative virtualisation environment I should be looking at which fully supports CentOS 4.x as a guest OS? And if so, does anyone have recommendations for a hosting supplier that offers that environment (ideally UK based). Many thanks Simon

I know a lot has changed over the past couple of years, and even monthly, and that Asterisk running within a virtualised environment is very happy indeed. If one would only be using SIP/IAX would Xen/KVM be the best solution ? / or perhaps VServer/LXC maybe advantageous due to binary hashing. Your thoughts would be very welcome. -- Thanks, Phil -------------- next part -------------- An HTML

I have a chipset which supports VT-d (Intel X58) and, according to my motherboard manufacturers, VT-d is enabled in the BIOS and listed as "Intel VT." The problem is that xm dmesg shows "I/O virtualisation disabled" and I get this error message when I try to create a domU with a pci device assigned: ''Error: failed to assign device: maybe the platform doesn''t support VT-d, or VT-d isn''t enabled properly?". I''ve made sure the PCI device backend driver is c...

Hi, I used to use KVM for virtualisation and have now moved back to it, but I have a problem. When i used to install the guest machine with virt-install i used to use the -x "extra args" part to set the console for the install and guest, but it no longer works. Here is the command i use: virt-install -n server01 -r 512 --os-v...

Dear mailinglist, I own a Gigabyte motherboard GA 970A UD3 with IOMMU support. Since the update XSA-36 (also part of the latest debian wheezy pkg), the IO-Virtualisation does not work any more as discussed on this mailinglist [0] and [1]. I like to ask, if there is an "official" solution in sight. I''m not sure about my alternatives. How "dangerous" is the mentioned IRQ sharing in [1]? May I just live with the NorthBridge disabled IO...

Niklas - Thanks! Yeah, your Github issue was very useful for me to understand what is probably causing our issue (the syscall chain done on every UDP packet). Very interesting that you're able to see around 90% of a Gig line on bare metal. Were you ever able to make any further progress on adjusting Tinc based on the investigation in https://github.com/gsliepen/tinc/issues/110 ? Martin -

...and XEN 3.0.2: I''m running XEN 3.0.2 on a MSI Fuzzy 945GM2 Mainboard (http://www.msi.com.tw/program/products/ic/ic_detail.php?prod_no=4) with a Intel Core 2 Duo Mobile CPU (T5500). When booting the mainboard BIOS says it found a EM64T CPU, which is AFAIK the code for a Intel CPU with Virtualisation Technologie. But whether Linux nor XEN detects this CPU as a VT CPU. Who''s right, the mainboard or Linux? Regards Falko _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

...ely and everything seems to work for the handful of users that have so far converted. If you also virtualise a Windows client on the same host as the Samba AD-DC then it should have its own virtualised network interface. This virtual-if can be assigned its own IPv4/v6 address as you see fit. Your virtualisation hyper-visor should take care of mapping the virtual interfaces to the actual hardware. However, this I have not done myself so my observations are inferences rather than experience. As far as HOSTNAME goes, no you would not use the same hostname on a virtualised host any more than you would give...

...table as the dom0. I have a desire to run at least RAID1 and ideally ZFS mirroring on the dom0 so I can have all the domU''s not have to worry about disk redundancy etc. My hardware : I have a brand new Intel E8200 core2duo and an Intel G33 chipset motherboard that the BIOS claims supports virtualisation, and 6GB of RAM and a pair of 500GB SATA HDDs - so I should be able to use HVM to run some domU''s without needing them to be xen-aware. I want to, in particular, get a SCO OpenServer 5.0.5 box running somehow in a virtual machine if possible with xen, if all else fails then with VMware....

...ss: - the application may check to see if a copy is already running and block a second copy starting up; - how to feed mouse / keyboard input to the relevant copy of the application. I''d like to be able to do this on Windows XP and am happy to wait for the next Intel / AMD chips with virtualisation support if that helps. Any pointers would be gratefully appreciated.

Hello, We all know linux distros will use most of the free memory available for caching stuff, I/O buffers etc (hence sites like linuxatemyram.com). In many virt scenarios we have some sort of memory deduplication mechanisms, such as KSM on KVM (don't know how it's called in Vmware). My situation is one where I need to cram up as many virtual machines as I can on a single hypervisor

Has anyone had any real-world experience using a VM to host storage for other VMs. For example, glusterfs running in a VM in domU on host A, replicating to another glusterfs VM on host B, with other VMs on those same hosts connecting to the glusterfs for their storage? It''s obviously not a very efficient way of doing things, but it might be an easy and flexible way to manage things in a
