Dear All I need to burn data cd on my CentOS and open the pdf file on my MS Windows client . My cd drive is at /dev/cdrom that is mounted as /mnt/cdrom . To this end , I issued as the following : #cdrecord -v dev=/dev/cdrom myfile But the file cannot be opened on ms MS Windows , nor the cd is usable afterwards . Can you please let me know how can I burn this data cd ? Thank you -------------- next

Hi All, The interface manual says - grant tables provide a generic mechanism sharing between domains. Subsequent lines suggest mechanism sharing between only unpriviliged domains. Can grant tables be used for this capability based shared memory communication between dom0 and domUs?

Hello all, I know that the question: Is it possible to run quemu inside Xen domU or run Xen domain 0 on quemu have discussed earlier in this mail list. As far as I remember this is possible except such a configuration where kquemu acceleration is in use. But what about HVM-capable systems? Please tell me are there the same restrictions for the hvm-capable systems? Thank you! -- WBR,

Hi list, I''m using Dom0 gentoo with xen 3.0.4 and xenman. I have several DomU working and it is really nice :) so all my DomUs are installed with disk images. Now i want to use an ISO to boot and install a linux system (or win). When i try to boot the DomU i dont have nothing, nothing relevant (for me) in logs and i can connect to the console. The state of the DomU is unknow. Any help

Hello, I''m setting up a Xen system since I have diferent choices to create the domU''s partitions: raw partition, lvm, files. I''ve done some tests with hdparm and it all seems to be the same. Can anyone, please, share with me what if the best method. Best regards, Luis _______________________________________________ Xen-users mailing list

Hi, For each domUs there is unique shared memory(2-way circular queue) and event-channel(one shared memory and event-channel per domU) or there is only one shared memory and interdomain event-channel(for every DomU)? regards: Amit _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hello Xen-Users! Is there a way to connect two DomU on the same real Host without using a bridge. Figurativly speaking I''m looking for a cross-over-cable for two DomU.

Chaps, Perhaps this question is a little basic for this list but I''m not really sure of the simplest method or best tool for the job. I''ve created some images with `dd=/dev/zero ....` and I''m using them for the domUs now. Some of them have been running for a few months with no probs. Trouble is that I''d like to create a separate partition within the domU.

Hi: we have following setup: 1. 2.6.16-33-based Xen 3.0.3/Xen-3.0.4 DOM-0 kernels. 2. Using LILO-mbootpack from USB we boot Xen-->DOM-0 setup 3. We mount harddisk and try to install xp.hvm While,we are successful with FCs as DOM-U, for XP we get, VBD (768) could not be connected. We do have max_loop count to 64 and enough loop devices. Note that above error is consistent on both 3.0.3

Hi all, I would like to know how to debug xen. To give some more informations, I would like to explain why I''d like to do this. I''ve compiled xen from source (3.1.x/unstable) and installed it on Debain etch. Furthermore I''ve installed 2 DomU, one HVM (Win2k3) and one EFW (Endian Firewall, RH-based 2.6.9-55 kernel). Both DomU''s are running fine for about 15

Hi all, I have installed SLES10 as a guest on a para-virtualized XEN 3.0.4. the host system is SLES10. Now I want to add a cdrom to the guest machine, when I do that by using "xm block-attach" it adds a new hard disk to the guest not a cdrom. Also I need to make the guest boot from cd. Thanks _______________________________________________ Xen-users mailing list

Just installed winxp in HVM under Suse 10.2. Now, I cannot access the CDROM drive even though it worked fine during the installation. Windows exploer show it as D drive, but when I put in a data CDROM, it keeps asking to install cdrom. Device manager shows the CDROM as QEMMU CDROM drive. Any suggestions?

Hello everybody! I´d like to know where "xm top" gets its information from. I want to get those informations (cpu-load, mem etc. from the domUs) and display them with php in a browser. So are the informations stored and updated in a textfile or something like that? Can anybody help me with this? Regards Alexandros _______________________________________________ Xen-users mailing

Hi Booting my Xen Dom0 on Debian Etch (Kernel is the prebuild one from bits.xensource.com), I found that only one cpu core (of two: dual core) is recognized by the (dom0-)Kernel. Googling this issue, I found on xen-devel-list that xen kernel is named smp but isn''t really doing so. Is there any (prebuild) kernel that I can use for smp? Thanks Gregor Reich

Hello, What is the better solution now to run linux domUs under Xen3? Using a VT hardware, sould I install a xen-patched kernel as I would where no VT extension, or use an unmodified linux guest system? Is there any performance difference between a Pentium D 3 Ghz with vt (9xx) and without it (8xx)? Regards, Slapic _______________________________________________ Xen-users mailing list

Hi! I'' ve a xen virtual machine, and i'' d like to assign cdrw device to it. My physical device on domain0 is /dev/hda, and in the configuration file i'' ve this: disk = [ ''phy:vg0/vx-disk,sda1,w'', ''phy:vg0/vx-swap,sda2,w'', ''phy:vg0/vx-data,sda5,w'' ] I'' ve tried to assign the cdrom to it in many ways i

Based on some tests we ran, it seems the biggest performance hit you get from running within domU is from disk I/O. We did some mysql read and write tests, and for both, our performance is about half that compared to native. Has that been others'' experience? Is there any way to make this better? We are using physical partitions. In contrast, cpu/memory tests appear to be near

Hello, Does anybody know something about Xen PV drivers for FreeBSD? As far as I know there are no stable Xen PV-drivers for FreeBSD at the moment. But what about experimental drivers? Please, if you have any information about this, tell it. I think it would be interesting not only for me but for all who runs HVM domains FreeBSD. And the second question. I run FreeBSD in domUs

Chaps, I finally have access to a VT enabled box. What would be the best way to get the most out of Xen and VT? A number of questions here. Bear with me. They may seem simple but all I did previously was get the source code, study it a bit, read the README and build from source. Now that I have a dual-core machine how does Xen know how to split resources for the instances? Does one give any
