HVM = fully virtualized. The question is, why are you using fully virtualized domUs? Why not paravirtualized (PV)? >>> On 2008/06/16 at 16:07, Rudi Ahlers <Rudi@SoftDux.com> wrote: Itamar - IspBrasil wrote: > why you''re using hvm ? its slow > > > > Rudi Ahlers wrote: >> Hi all >> >> I''m running CentOS 5.1 x64 + Xen 3.0 & I

Hi, folks, I''m attempting to run an e-mail server on Xen. The e-mail system is Novell GroupWise, and it serves about 250 users. The disk volume for the e-mail is on my SAN, and I''ve attached the FC LUN to my Xen host, then used the "phy:/dev..." method to forward the disk through to the domU. I''m running into an issue with high I/O wait on the box (~250%)

Well, first, you''re going to have a lot of trouble getting anyone to touch SCO these days. With all the legal stuff they''ve pulled over the past couple of years I''m sure that no one is going to be eager to get in their way on purpose. What issues are you having getting SCO to run under XEN? Theoretically, with XEN HVM support, you ought to be able to run just about

I''m running xen on SLES10SP2. It''s been much more stable than SP1, but I still occasionally have issues. For example, one of my servers (8 CPU/32GB RAM) has five sles pv domUs and five fully virtualized windows 2k3 domUs. It had been up for almost 60 days. Yesterday afternoon one of the sles domU''s stopped responding. I went to check on it and I couldn''t using

I''m running SLES10 SP1 and have been using file:/ for my file-backed domUs. The domUs sit on a shared OCFS2 SAN-backed filesystem and are run on my three or four XEN servers. I''m having issues with the loopback devices not being released when the domUs shutdown or migrate, so I decided to switch over to tap:aio for my file-backed domUs. This isn''t working, either.

Hi Is it true that the GPLPV drivers is incompatible with QCOW images? The Windows DomU works fine with raw standard "file:/" images, and paravirtualized Linux DomU works fine with QCOW and raw images. If i use QCOW images with my Windows DomU''s i get a stop error: 0x00000007b (inaccessible boot device). It looks like the blkback.3.hda process, that normally starts with

I am not clear with the working of hypervisor xen. How does an instruction executed by kernel in Ring0 of DomU gets mapped or executed by hypervisor and then is excuted in Dom0. Is this thing some where on the wiki page? -- Tapas _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Microsoft has their "boot" version of their iSCSI software initiator. Apparently this still requires that the network card be iSCSI Boot "enabled." Intel seems to be the only obvious company out there supporting it on their Server adapters - I was wondering if there are any thoughts/plans on implementing iSCSI Boot functionality in the HVM Boot ROM? Or maybe there''s

1) No, not necessarily. Many VM systems (Parallels, VMware, even XEN HVMs) emulate Ring 0 access for the operating system running on top of it, so there isn''t any reason for direct hardware access. However, you really should grab some older or cheaper hardware and install Xen directly on the hardware - it will be very, very slow running inside parallels. 2) There really isn''t

Hi, DomU is a Win2008 R2 64 When i install the GPLPV drivers the network latency goes from 15ms to random numbers up to 1200ms and eventually dies. If you run a ping from the DomU to another host the network stays alive but the high latency is still there. Further more if i try and uninstall the network driver i am unable to use the old one (realtek) as it cannot detect the device.

Hi,All, I installed a guest os with full-virtualization and a local volume as the disk, now becuase of poor performance, I want to change the full-virtualization guest to para-virtualization, so I just changed the config file to boot the guest os with para-virtualization, but it fails to boot. but how can I convert the full-virtualization guest to para-virtualization without reinstall the os,on

Hey, everyone, I''m having some issues with a Xen DomU right related to performance. We have an application that cross-compiles a Linux distribution from scratch for embedded systems. We''re attempting to run this application inside a Xen DomU (paravirtualized, modified guest kernel), and the performance is really bad. The culprit seems to be high I/O wait times related to the

Pasi, Thanks for putting that wiki page together for the dom0 kernels - it's something that has long been needed for pulling together information on those kernels. I know it's always a chore for me to find info on how to get/build a dom0 kernel if I don't like the one that's included with a distribution. Thanks! -Nick >>> On 2009/07/07 at 00:50, Pasi

Well, I seem to have developed a strange issue with the GPL PV drivers in Windows. I''m running Xen 3.2 on SLES 10 SP2 and running some Windows XP HVM domUs. Most (12-15) of my Windows machines work just fine. Two of them, though, have started exhibiting a strange behavior with intermittent network connectivity. Basically, the network starts up and connects initially. After some
