Description of problem: Trying to create a new VM when there were on 3B left on /. After deleting some files and having 5GB of space on / virt-manager still thinks there are only 3GB of space left when trying to create a new machine. Version-Release number of selected component (if applicable): virt-manager-0.7.0-5.fc11.i586 How reproducible: always Steps to Reproduce: 1. create new VM in virt-manager. On step 4 of 5 the remaining space on / is shown. 2. free some space on /, create new VM and verify that the size didn't change in step 4 Actual results: calculated free disk space stays the same Expected results: calculated free disk space is re-checked whenever a new VM is created Additional info: free space on boot: sassmann@x60:/> df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 20G 16G 2,6G 87% / free space later on: Filesystem Size Used Avail Use% Mounted on /dev/sda3 20G 14G 4,6G 76% /
Ah, this is the "XXXGb available on the host" thing I guess to fix this we'd just need to poll every five seconds or something Adding to F12VirtTarget
Why would we need to poll for the remaining disk space every so often? We could just update the value whenever necessary. Polling should be considered the last of all options because you constantly need to get out of idle state. I'm not sure if there are any other places where you need the free disk space value. As of now I've only seen it during VM creation. What's your opinion Mark? Btw, thanks for considering all my RFEs!
(In reply to comment #2) > We could just update the value whenever necessary. Define "whenever necessary" IMHO, when the label is visible we'll need to poll to keep it up to date
By "whenever necessary" I mean whenever a window shows up that interacts with the remaining disk space value. The value is unlikely to significantly change during the creation of a VM but I don't know where else it might be used. The value could be updated every-time _before_ it is actually read, which would avoid polling.
Fixed in virt-manager-0.8.0-5. While the 'New VM' wizard is up, we poll every 3 seconds to make sure the value is current. Updating it only at access time doesn't fly, since the value is used to limit the storage size spin box, and has to be deliberately adjusted.
