Hi, Please try creating a ramdisk with xennet and xenblk preload options and include this ramdisk in VM configuration file. (you can use mkinitrd, man pages).

Here is another one. I installed Xen 3.2.1 on 64 bit FC8. Now when I try to create a guest domain I always get the error: "Error: Device 0 (vif) could not be connected. Hotplug scripts not working" I got the same error ehrn I tried to create the guest with virt-install or even manually using "xm create". I have the same configuration on a 32-bit FC8 machine with nor problems. I also found several posts on the mailing list but none was useful to my problem. I tried both HVM and para-virtualized guests. I only got the HVM guests to run when I changed the parameter vif=[,,] to vif0=[,,]. But obviously I could not get the guest to use the network. When I used the same trick with my para-virtualized guest the kernel hangs during load time while it waits for "XENBUS" to start. I have udev installed on my machine. i really wonder why does in needs hotplug for!!! Any help??

Partitioning and LVM Question To: xen-users@xxxxxxxxxxxxxxxxxxx Message-ID: <48603865.90109@xxxxxxxxx> Content-Type: text/plain; charset=windows-1252; format=flowed Hi everyone! Where does Xen save the "DomU state saves"? I have been trying to figure out the most time-proof partition scheme for my set up and I was wondering if I could make the folder(?) where Xen 3.2.1 save it's DomU states saves (what is the right expression for this?) and put it on its own LVM partition here is why: I only have 2GB RAM on my ML570. I will be upgrading memory as I need (up to 32GB). If Xen saves its DomU-saves to the Dom0's partition then as my server receives more RAM and I will allocate more memory to DomUs that folder with in Dom0 will expand to such large proportions that it chokes of Dom0's hard drive space and crash the system. If I have a LVM in an automatic mode resizing the partitions as needed I should always be in good shape when it comes to that. Of course this could all be avoided if Xen saves the states to the DomU partition and reads them from there accordingly. Somehow I suspect that Xen saves the DomU state saves somewhere on the Dom0 partition by default (if you only have a "/" partition containing the whole Dom0). I'm still attempting to figure out the best partitioning scheme for my boxes...any help would be appreciated. Thank you in advance, Sincerely, Evan Miller +++++++++++++++++++++++++++ Hello Friends, After over 30 hours of scouring the web for a recent comprehensive guide of installing Xen on Debian Etch I feel like I have no choice but to post here (my first mailing list post!). I found many good guides, but it seems that they all lack: A. recommended partitioning scheme and/or B. LVM set up ************************************** I was following the http://www.howtoforge.com/debian_etch_xen_3.1 guide and everything went well for a while, but the [new] Xen version was incompatible with some of the instructions so I set out to look for a more recent guide and found out that there is a much easier way to install Xen (from sources) now and that I should use LVM. The above link was the only one that gave the detailed partitioning recommendations I needed: * /boot 150 MB (Primary) (Location for the new partition: Beginning) (ext3) (Bootable flag: on <-- important, otherwise your system will not boot!) * swap 1GB (Logical) (Location for the new partition: Beginning) * / 3GB (Logical) (Location for the new partition: Beginning) (ext3) * /vserver the rest (Logical) (Location for the new partition: Beginning) (ext3) Unfortunately it is missing instructions for using LVM. This guide mentions LVM, but has proprietary partitioning scheme and old Xen version: http://www.d7031.de/text/xen_with_lvm_under_etch.shtml http://www.cosmocode.de/en/blogs/gohr/20070130123639/ - This guide gets very close covering both, but it is outdated and I am wary about mixing the original guide's ( http://www.howtoforge.com/debian_etch_xen_3.1 ) partitioning scheme and this one. I also was hoping to achieve the internal routing and the best guides that seem to cover that are the original guide I mentioned and the http://xgu.ru/wiki/Xenomips/en (later one is a bit beyond me at this time). ************************************** I am sorry for the convoluted first post - I think it reflects my mind state at this time! XD I would like to introduce myself to all of you: My name is Evan, I am a *NIX newbie, I have been "messing about" with Linux distos since 2001 and about as long with FreeBSD. Unfortunately I have not ventured far beyond GUI and always came back to Windows XP. Lately I was put in charge of creating a test set up for our startup so I have been forced to learn many things at once while producing some sort of positive results on a very tight schedule. We have decided that a Xen setup running on top of Etch was the way to go, but actually implementing such a setup has proven to be very challenging. I would appreciate any help, but please keep in mind my limited linux and non-gui experience (I'm just learning to appreciate vi). ************************************** Hardware: I have 2 Xen candidates: 1. ML570 2G Server with 4 2.4GHz Xeons, 2GB PC 2100 Ram (6GB more coming) and 6 15k 73GB SCSI drives (and 6 more to come) running on the the LSI 320-2 controller in Raid0 soon to be backed up on to 2 SATA 2 1TB Drives running off a SATA 300 Promise controller. 2. Intel Pentium D 820 (dual core 2.8GHz) based desktop with 1GB ram and on-board sata 150 running a 240GB SATA drive (more drives and memory will be added). The P5LP-LE motherboard ( http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00864946&lc=en&cc=us ) supports VT chips so at some point we may upgrade this box to Intel VT cpu (I am not sure if I will have to reinstall the VT enabled Xen at that point or not). Eventually I would like to run a mix of: http://lxer.com/module/forums/t/24435/ and http://xgu.ru/wiki/Xenomips/en and have the ability to move live machines from the ML570 to the Desktop 820 D system at night to save on power. ************************************** For now I would be happy with a solid partition recommendation to get me started on the way to these goals. I will start with the Desktop D 820 system with Etch running as Dom0 on a 250GB SATA drive. I would like to eventually have a GUI access to managing Xen DomUs so I thought I would mention this encase a 3GB root partition ( http://www.howtoforge.com/debian_etch_xen_3.1 ) would be too small. Keeping all above in mind what would be the recommended partition scheme for the 250GB drive? ************************************** Thank you in advance, Sincerely, =) Evan Miller +++++++++++++++++++++++++++ ------------------------------ Message: 3 Date: Tue, 24 Jun 2008 11:03:37 +0300 From: Igor Chubin <igor@xxxxxxx> Subject: Re: [Xen-users] about module nVidia GeForce 8400 G in Xen To: Christopher Isip <cmisip@xxxxxxxxx> Cc: ??!?

Just set the > environment variable. You talk about export IGNORE_XEN_PRESENCE=1 right? I have downloaded drivers from the page: http://www.nvidia.com/object/linux_display_ia32_173.14.09.html and have tried to install it with the variable IGNORE_XEN_PRESENCE set to 1. export IGNORE_XEN_PRESENCE=1 sh NVIDIA-Linux-x86-173.14.09-pkg1.run --x-module-path=/usr/lib/xorg/modules/ I have got the same error message "Xen was detected; I don't want to continue" or something like this. Have you installed NVidia drivers in this way? What is the kernel version on the system where you have installed it? May it be due to my kernel is too old? $ uname -a Linux cholpon 2.6.18-4-xen-686 #1 SMP Thu May 10 03:24:35 UTC 2007 i686 GNU/Linux Any other ideas?

Not quite sure what you mean here... If you only do bridging in Dom0 and your VMs are on different networks then packets may need to go out of Dom0 in order to route them. But that depends on how you network is set up, it is not a Xen issue. What setup do you run in your Dom0? Do you use the bridge? > How can that > path > be shortened?

Yes, for example, if all your guests are on the same networks then the bridge would pass them directly to the correct destination. If you need to have the guests on different networks then you could do routing in Dom0. > Finally, what brands are there for Virtualization-aware NICs? Maybe I > will > buy one.

If yes, is it a HVM or a PV guest? Check in xm list whether your domain is created and running. What does xm create -c show? If xm list shows your domain and still you are not able to connect to the console. Use a vncviewer to attach to a console. For example : vncviewer 12.0.0.1:5900 Use 5901 if 5900 is not working. As you keep creating additional VM's increment the screen number 590x. I guess this helps. Venkat ================================ Venkata Kumar Duvvuru, LSI Engenio, Adv. Development, Bangalore.
