Which Virtualization For Desktop

Sep 15, 2008

This is a little bit Offtopic here but maybe it's okay to ask my question.

For my GUI software development i need a virtual server solution. It must run WinXP, WinVista, LinuxI386, LinuxAMD64, FreeBSDI386, FreeBSDAMD64 and Solaris.

I'm currently running VMWare with all this systems. But their KVM tools are very instable - especially when waking up from hibernate etc. They eat the key/mouse focus and the only way to get any reaction is often a hard shutdown.

How good are the other Virtualization Kits? I heared that FreeBSD does not work on VirtualBox? I'm especially interested in Xen but i'm not sure if this is good for Desktop use. Seems that it is promoted almost exclusively as a server solution.

To Do Virtualization Inside VPS

May 12, 2009

I have this nice vps, but its on linux, and I always wanted to run windows apps on the vps, because of the nice configuration. I already tried wine, but most of my windows apps don't work, cuz they require .net framework to run.

I tried to instal vmware server and virtualbox, but both of them complain about a kernel problem, they are unable to locate my kernel source, so they can't run.

I am linux newbie, and i am running on a centos 5 operating system.

Some people say its impossible to run virtualization 'inside' virtualization, but i already read some people that say its possible.

Virtualization Platform

Mar 29, 2009

In another thread somebody had mentioned something about Citrix Xenserver utilizing shared iSCSI storage with multiple hardware nodes. I think this is a very intriguing concept, but is there anything open source or less expensive that you have used to accomplish similar resource virtualization?

Whether citrix or not, describe your setup!

Virtualization WIN 2008

Mar 5, 2008

I have a machine with 2*Xeon 2.66, 16GB Ram, 146GB Raid 1, 292GB Raid 10.

This machine will be used to run Mysql (32bits or 64bits) and MDaemon (32bits only).

I have 2 options to choose and I'm not pretty sure which is better.

a) Win 2008 32bits Enterprize using PAE for ram support and running Mdaemon 32 and Mysql 32.

b) Win 2008 64bits standard having virtualized a win 2008 64 bits for Mysql 64 and a win 2008 32 bits for MDaemon 32.

Apache X Virtualization

Jun 26, 2008

We usually find some constrains using Apache/cpanel (1.3.41). Basically, we serve simple php codes and few images.

We usually setup our server to use lighttpd for static content and apache for dynamic content. Ok, due to some complex requirements on mod_rewrite we use that setup.

But frequently we see our apache reaches it limit and slow down with 0 idle servers. Specially as we have about 270 requests/per second on apache. Our load is low, barely passes 1,2 of load for small periods, our memory ok, our I/O is fine.

But we almost always reaches the 0 idle servers. Until now, our best config was:

Timeout between 60-120
KeepAlive Off
MaxKeepAliveRequests 1000
KeepAliveTimeout 15
MinSpareServers 50
MaxSpareServers 200
StartServers 50
MaxClients 256
MaxRequestsPerChild 80

As we clearly see that our server is under usage, I was wondering if it's a limitation on Apache or if I put virtualization on my server and run two apache webservers as cluster I would get better results.

So what do you think about guys? It's a matter of optimization (what could I do better for this httpd.conf setup?) ? Or cluster with virtualization would deliver what I'm looking for.

Microsoft Licensing For Virtualization

Nov 3, 2009

Microsoft said this about Microsoft Licensing for Virtualization

Windows Server 2008 Datacenter
Run any number of software instances in physical and virtual operating system environments on a server.

Now,I have some questions:

1)Is this method of licensing just for hyper-v or we can use it on vmware ESXi or Xen?

2)How we can use Microsoft Volume Licensing on Vmware ESXi and Xen?

3)What is the best solution for windows virtualization?(vmware esxi or hyper-v or xen)

4)what is difference between xen and xenserver?

5)which control panels we can use for hyper-v,vmware ESXi and xenserver?

Virtual Iron Virtualization

May 23, 2008

Basically I need to virtualize a single new dell server. One virtual server needs to run windows 2003 server standard and Microsoft SQL 2005. The other virtual server will run CentOS Linux with a perl and PostgreSQL application.

The dell server is going to have two quad core xeon processors (8 cores total), 8gigs of ram, and two 15,000rpm SAS drives.

I came across Virutal Iron which is free for the single server instance and seems like it will do the job well. Has anybody used it? What is performance like? Seems to run a Java backend so wondering about the performance there.

Any other recommendations? I looked at VMware but the cost is so high, and probably more then I need, since I only need to virtualize a single server.

Virtualization Vmware And Dos & Syn Attack

Oct 17, 2007

How will VMware ESX Servers handle a dos, ddos or syn attacks? Will it compleatly crash all VM running on the server just becouse one VM and its ip interface is attacked and make file systems monted on a san or nas to be corrupt becouse of the traffic on the local network will be downgraded becouse of all packets that passes to the VM:?

Does vmware have some protection tools for this kind o attacks or does this kind of virutalization only work in a an lan that is protected from Internet?

Will 2 dedicated nic solve this?

Virtualization Solution? VMware, Virtuozzo, Xen..?

Jan 12, 2007

I'm running a dedicated server and the main site on the server relies on Windows OS. The site is not fully utilizing the potential of the dedicated server, so I'd like to put some of my other sites on the same server and eliminate the other (shared) hosting I've been using.

Here's the catch... For the other sites, I'd like to run WHM/Cpanel which requires Linux.

If I understand correctly, this leaves me with having to decide on a virtualization solution, which I know nothing about. Some options I have been given are VMware, Virtuozzo, and Xen.

Would you suggest one of these or a different solution entirely?

Virtualization --48Gb @ 1333Mhz Or 72GB @ 800Mhz

Oct 26, 2009

So when buying nehalem servers, if you populate 6 rdimms, you can run at 1333Mhz, if you populate 18 rdimms, 800 Mhz (12 rdimms, 1066mhz)

So what do you do for virtualization? the reality is most of the time 48gb is going to be enough for virtualization (that would run 12 4GB servers or 32 2GB servers) and i think at 64gb or more, CPU starts to become a limting factor, but the price of 48GB @ 1333 is slightly more than 72GB @ 800. So what are you guys doing out there? do you go for the performance or do you go with the overkill of memory (that might sometimes come in handy but you probably wont use it all -- more likely just give your VMs more memory for the fun it)? The problem is the 1333 Mhz vs 800 Mhz performance.

Our current environment is a bunch of 16GB servers (50xx chip) and the limitation on us virtualizating more per host is the memory. So I know 48GB is going to be very much welcomed and I think we could use more.. 64gb would be ideal, but we will be happy with 48@1333, but 72GB sounds interesting too, there might be some scenarios where we could use that 72GB although i think performance will shift from memory limitation now to CPU

Do you think if we buy 800Mhz 72gb we will ever look back and think "wish we bought the 48gb 1333 rdimms and not these 800mhz ones"?

I Have Lots Of Bandwidth, But My Host Is Slow - Should I Pay For Virtualization

Sep 12, 2007

I use a host that gives me way more bandwidth and space than I need, but it is still super slow. It's Dreamhost who is known for charging very low fees and promising the world. Although my sites do load and I get unlimited everything pretty much, I can't stand the slow loads.

They have offered me virtualization of my server so I can create my own virtual server with 150Mhz and 150MB of dedicated CPU/memory for $15 more a month... do you think that will speed me up a lot or should I just suck it up and pay for a better host that doesn't pimp themselves out so badly?

Virtual Private Server (VPS) Providers: Which Virtualization Implementation?

Jul 25, 2008

I'am curious which (semi) virtualization implementations you use, and why! Just out of interest...

- VMWare Infrastructure 3
- VMWare ESXi
- VMWare Server
- Virtuozo
- OpenVZ
- XEN
- Linux vserver
- FreeBSD jails
- append the list, if I forgot some

What have been the reasons for your decision? Where do you see disadvantages using other than your choice?

Virtualization - Enterprise Installs? VMWare, Xen, Virtual Iron?

Aug 14, 2007

A company i am working with is looking to install a VMWare setup comprising of something like this :

6x Dual Proc Quad Core Nodes with 16GB RAM
2x Clustered iSCSN SAN Nodes

I am intending on purchasing the full suite including DRS/HA/VMotion.

Now this is all well and good but the software pricing is absolutely horrendous! So my question to you chaps is :

Is anyone using the latest Virtual Iron or Xen Enterprise in a high end environment?

Obviously VMWare is the market leader, the big boys are using it and its something you can bank on. (literally! HSBC use it ALOT!)

Is it even worth looking at VI/Xen for something like this? The cost would be like a quarter of the total cost of a VMWare license.
