libvirtd is happy enough to run the second and/or third disk if I manually insert via virt-manager or cli and VM sees the disk fine, so this issue is how to get xcat to start an ephmeral VM that doesn't have a a porfile saved on a hypervisor?
I can do this with lvm using vmstorage=phy:/path/tol/v1|phy:/path/to/lv2 on a node yealds to compalints from xcat, all I'm looking for is the equivalent for a file based disk image _________________________________ Douglas Myers, IBM Special Events - Smart Cloud BMS Lead _________________________________ "It's not an opportunity if it doesn't scare you a little bit" |------------> | From: | |------------> >--------------------------------------------------------------------------------------------------------------------------------------------------| |Xiao Peng Wang <[email protected]> | >--------------------------------------------------------------------------------------------------------------------------------------------------| |------------> | To: | |------------> >--------------------------------------------------------------------------------------------------------------------------------------------------| |xCAT Users Mailing list <[email protected]> | >--------------------------------------------------------------------------------------------------------------------------------------------------| |------------> | Date: | |------------> >--------------------------------------------------------------------------------------------------------------------------------------------------| |08/06/2015 03:41 AM | >--------------------------------------------------------------------------------------------------------------------------------------------------| |------------> | Subject: | |------------> >--------------------------------------------------------------------------------------------------------------------------------------------------| |Re: [xcat-user] KVM storage question | >--------------------------------------------------------------------------------------------------------------------------------------------------| I think you first need to figure out what libvirt can do for you since xcat totally following it's functionalities.

The design has the hypervisors seeing gpfs as local storage, and when I add a single raw image file and start the VM with it, everythign works fine. The problem is, several of these VMs have two or three logical volumes presented as disks, sd[abc]. When I attempt to convert the second lv to a file, the conversion works fine, but I'm missing the proper syntax to add it to the vmstorage object: vmstorage=/gpfs/root/z10071_rootvg.img|r/gpfs/app/z10071_appvg.img When attempting to power up, I receive this message: z10000:~ # rpower z10071 on z10071: Error: internal error Only 1 ide controller is supported If I try to set the vmstoragemodel to scsi, xCAT will boot the VM but the VM cannot find it's root disk. If I revert to a single disk and remove vmstoragemodel I can successfully power on and boot into OS. So how to I add more than one image file as a disk? (Yes, I know, should be using virtio disks, these are legacy machines, newer VMs will hopefully be using it) _________________________________ Douglas Myers, IBM Special Events - Smart Cloud BMS Lead _________________________________ "It's not an opportunity if it doesn't scare you a little bit" ------------------------------------------------------------------------------ _______________________________________________ xCAT-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/xcat-user ------------------------------------------------------------------------------ _______________________________________________ xCAT-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/xcat-user
