Description of problem: An error is given when trying to install a guest to a non-sparse logical volume using virt-install: [root@localhost ~]# virt-install --name=test --disk=pool=guests,size=20,sparse=false --cdrom=/mnt/OS.iso --ram=2048 ERROR Error with storage parameters: Sparse logical volumes are not supported, allocation must be equal to capacity Version-Release number of selected component (if applicable): python-virtinst-0.600.0-24 How reproducible: Steps to Reproduce: 1. Create volume pool 2. Run the above command Actual results: ERROR Error with storage parameters: Sparse logical volumes are not supported, allocation must be equal to capacity Expected results: Guest is created Additional info: This appears to be a problem introduced with virtinst-LVM-Show-warning-when-allocation-0-and-allocation-ca.patch: @@ -1350,7 +1350,7 @@ class LogicalVolume(StorageVolume): def __init__(self, name, capacity, pool=None, pool_name=None, conn=None, allocation=None, perms=None): - if allocation and allocation != capacity: + if allocation is not None and allocation != capacity: raise ValueError(_("Sparse logical volumes are not supported, " "allocation must be equal to capacity")) StorageVolume.__init__(self, name=name, pool=pool, pool_name=pool_name, Allocation is hard-coded as 0 on line 1478 in cli.py, so this looks like it will always fail: volinst = vc(pool_name=pool, name=vname, conn=guest.conn, allocation=0, capacity=(size and size * 1024 * 1024 * 1024))
I can reproduce bug issue with following package: python-virtinst-0.600.0-24.el6.noarch steps: 1. Create a lvm pool: # virsh pool-info lvmpool Name: lvmpool UUID: 48078a48-ca27-2d50-d5b8-bdaed7d1733a State: running Persistent: yes Autostart: yes Capacity: 10.00 GiB Allocation: 0.00 Available: 10.00 GiB 2. Use virt-install to install a guest on logical volume # virt-install --name=test --disk=pool=lvmpool,size=10,sparse=false --cdrom=/iso/RHEL-6.6-20140926.0-Server-x86_64-dvd1.iso --ram=2048 ERROR Error with storage parameters: Sparse logical volumes are not supported, allocation must be equal to capacity Result: failed to install guest and showing above error. Then try to verify this bug with new build: python-virtinst-0.600.0-26.el6.noarch steps: # virt-install --name=test --disk=pool=lvmpool,size=10,sparse=false --cdrom=/iso/RHEL-6.6-20140926.0-Server-x86_64-dvd1.iso --ram=2048 Starting install... Allocating 'test.img' | 10 GB 00:00 Creating domain... | 0 B 00:01 ..... Result: virt-install create guest using non-sparse logical volume successfully. # virsh vol-info --pool lvmpool /dev/lvmpool/test.img Name: test.img Type: block Capacity: 10.00 GiB Allocation: 10.00 GiB so move this bug from ON_QA to VERIFIED.
