Configurable Cloud VM is a small command line tool for automatically creating development and demo environments for complex projects. The tool sets up these development environments inside a virtual machine which it automatically creates on the user’s host computer. This avoids polluting the user’s host machine with components from the chosen development environment and provides a clean, predictable and repeatable environment in which this development environment can run.

Xenial image no write on mounted drives #50

Closed ganeshmaharaj closed 3 years ago

ganeshmaharaj commented 6 years ago

Just leaving it here so that others are aware of it. It seems there is an issue with libvirtd used in ubuntu releases that is causing the mounted drives to be readable but prevents us from writing to them. https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1559317

the bug doesn't show clearly the status of the bug or the release of libvirt that fixes it. But here are the info about my env. Xenial 16.04

sudo apt-cache policy libvirt-bin

@ganeshmaharaj ccloudvm doesn't use libvirt. I've only seen one problem with ccloudvm writing to 9p mounts. I seem to be unable to write to the top level directory in the mount. So if I mount /home/user I cannot write to /home/user in the guest but I can write to /home/user/src, where src is a directory.

Are you having problems writing to 9p mounts? There was also a bug that I fixed a while ago which prevented the guest from writing to a 9p mount if the user on the host was not the first user on the host machine. This has now been fixed.

@markdryan duh!! ofcourse you are not using libvirt. face-palm. yes, 9p is unable to write to the top level mount but is able to write to the usbdirectories. I don't seem to recall having this problem 2 weeks ago and i have been mounting the same directory the same way.

I am going to guess this issue is no longer valid and can be closed. As such, I am doing the same. Feel free to re-open the issue if it is needed.
