similar to: handling mac addresses and guid''s

Hello all, There''s been many posts lately about problems that stem from either duplicate macs, non static macs and other networking issues that would be averted if a mac was specified upon vm creation. I''ve been using this little function I wrote in my shell scripts that setup dom-u''s from a csv file and its worked rather well, lets you control the prefix and

Hi, I must find a way around the way live migration now uses ssh. I tested it and I see high cpu usage by SSH and overall sense of things being slow. My prod systems have a dedicated, fast link for live migration, but with ssh it would be crippled down to a <1Gbit. Does anyone have a working example of how to not use SSH as the transport layer? I guess this is what the -s option is for, but I

Any one has faced same problem?? -- Thanks Vipul Borikar "Our task must be to free ourselves...by widening our circle of

Hello, Currently it seems that the drbd disk type with Xen''s XL toolstack (vs XM) to get the automatic promotion/demotion behavior of drbd devices is not supported. Is there something I can tweak with the block-drbd script to get this to work?

Hi, I seem to have an interesting issue with vif-route. This is after an update to Xen 4.2.1, switching from xm to xl. I have 10 PV domUs on the host and two FreeBSD ones. All the PV domUs are now working nicely. Since FreeBSD has always been just slightly broken as PV I chose a HVM domU for those, but with PV drivers. Those PV drivers all blew up now after the upgrade. I''m now trying

Hi Folks, Anybody have any recent experience building a small cluster that combines GlusterFS and Xen (with bonus points for a Debian environment)? We''re getting ready to shift from a 2-node Xen/Pacemaker/DRBD environment to a 4-node environment - and I''d really like to be able to create/migrate/failover/delete VMs transparently across all 4 nodes. Seems like Gluster might

Hi All, I want to test REMUS over XEN, I would like to know the basic steps to be followed .

I am using XenServer6, and I need to get performance equal or close to what we get on the hardware, especially with large files. Are there any hints host side or guest side to increase performance. What should I look at? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hello, While using xen 4.1-testing.hg (r23202) I noticed that the ''vifname'' config value is not handled by xl, but is handled by xm. Is there a workaround or patch for this? My firewall and scripts depend on static vifnames. XM works good - it adds multiple interfaces to multiple bridges and configures them appropriately. But with xl it differs -- here only tap devices are

Greetings! I''ve got a FreeBSD-based (FreeNAS) appliance running as an HVM DomU. Dom0 is Debian Squeeze on an AMD990 chipset system with IOMMU enabled. The DomU sees six physical drives: one of them is a USB stick that I''ve passed through in its entirety as a block device. The other five are SATA drives attached to a controller that I''ve handed to the DomU with PCI

Hi, first i will explain my experiment : We have ESX server running virtual machines .We want to migrate to XEN. As i did not found any tool for transfering ESX to for example real server, or better to XEN --> please correct me if i am wrong , i found following approach : i will inside virtual machine on ESX boot from Live-CD of CentOS , using dd i will transfer images trought scp to CentOs

Hi there, I have been browsing for web hosting and I found some firms (one of them is <http://www.hub.org>) offering 'virtual server hosting using FreeBSD'. They say that virtual server is different from virtual host, for the first is a completely separated enviroment, like a standalone server. I am a newbie on FreeBSD, I search at the archive and Google for this info; and at this

Hi! Say I export an LVM logical volume from dom0 as /dev/xvda to the domU: disk = [ ''phy:xenimages/stan,xvda,w'' ] No I can lvresize xenimages/stan in dom0, but the domU stays ignorant of this change. How could I propagate the resize to the domU without rebooting or temporarily breaking its connection to /dev/xvda? Sort of a SCSI rescan, perhaps? -- Thanks, Feri.

Does anyone know what is the latest version of dom0-kernel, that supports fully xenpm hypercalls? I tried from 3.0 to 3.3 with xen-4.1.3, but none of them has xenpm working. On the other hand native kernel cpufreq is OK with all of them. My CPU is Xeon family 6 on PowerEdge 1950 III box. Regards, Dimitar Kazakov
