similar to: RE: live migration with xen 2.0.7 with fibre channel onDebian - help needed

Hi, I''d like to test the stability of live migration during heavy load of domU. scenario: - both dom0s and domU are running on Debian Sarge. - script on dom0 triggers live-migration to the other dom0 - domU is running I/O tests, e.g. bonnie++ - domUs root- (ext3) and swap fs is stored on two partitions in a san - san is connected using fibre channel cards to both dom0s - san in dom0

Hello there! I made Debian, Xen 2.0 and CLUSTER/GFS work together :). I wrote this little tutorial to help you setup yours. Any feedback is welcome, except comments about W3C validation of my code :p Note that I am talking about compiling CLUSTER with your XEN kernel, I don''t explain how to setup a working cluster. You can find how to setup those in official RedHat docs. You will see,

Has any one had any success with cow implementation in xen ? I found this somewhere http://www.atconsultancy.nl/cowloop/, has anyone tried it out with xen ? -- regards, Anand _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi! I''m currently preparing to xen installation. In the system that I''m going to set up, there will be a need to copy large amounts of data (therefore I want to avoid using network) from domUs to the dom0 (one way only). Mounting a filesystem RO, when a domU has it mounted RW is probably asking for trouble. Therefore I was thinking about using some remounting protocol similar

Are there people currently managing multiple Dom0''s and making significant use of migration? I''m loking at a potential setup of 16 or so physical systems with perhaps 64 or so virtual systems (DomU''s I suppose Dom0 is also a virtual system if I understand thing correctly, but that''s no twhat I mean here). It seems to me that making heavy use of migration for

Hi, I need to do a test with SLES 9 running in a domU very quickly and don''t have much time. Is there anybody out there having experience in installing SLES 9 into a domU? Or way better, maybe has a already running guest installation for download?

Hi, I am currently making some i/o performance tests within domUs with iozone3. One scenario is a domU with file-backed VBDs (root and swap) as sda1 and sda2 lying on an nfs-kernel-server (2.6.14.4 - Debian Sarge). The exact iozone command is: iozone -a -R -b result.xls -f /tmp/iozone.test -n 1m -g 256m -i 0 -i 1 As soon as the iozone-test comes to a filesize of 132M, the complete! system

I have added a specification of probes for the fibre channel COMSTAR port provider to the DTrace section of wikis.sun.com. The proposal may be found here: http://wikis.sun.com/display/DTrace/fibre+channel+Provider I welcome feedback regarding this proposal. Thanks, Sam

For quite some time I?ve been using FreeNAS to provide services as a NAS over ethernet and SAN over Fibre Channel to CentOS 7 servers each using their own export, not sharing the same one. It?s time for me to replace my hardware and I have a new R720XD that I?d like to use in the same capacity but configure CentOS 7 as a Fibre Channel target rather than use FreeNAS any further. I?m doing

In principle, will Xen handle virtualization of Fibre Channel HBA''s? Say I have a physical server with a single FC HBA installed. If I create two domains, will XEN virtualize the HBA so that both of the domains can talk to the FC fabric? -M. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hello, I have been looking around all day and lot''s of things are being thrown at me such as npiv and vscsi and such. I have an HITACHI,DF600F SAN which goes via two switch fabrics and plugs in to the dual port Qlogic HBA on the server(s). I have 4 Dell 2950''s at current which are under-utilised.
