From 24cb65efc3c34e24fc653779a4d42cf4f31c6737 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Fri, 21 Mar 2014 13:54:53 +0100 Subject: Make /dev/kvm optional MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The daemon now creates /dev deterministically (thanks!). However, it expects /dev/kvm to be present. The patch below restricts that requirement (1) to Linux-based systems, and (2) to systems where /dev/kvm already exists. I’m not sure about the way to handle (2). We could special-case /dev/kvm and create it (instead of bind-mounting it) in the chroot, so it’s always available; however, it wouldn’t help much since most likely, if /dev/kvm missing, then KVM support is missing. --- src/libstore/build.cc | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'src') diff --git a/src/libstore/build.cc b/src/libstore/build.cc index 973e7a122f5f..e846995f76bb 100644 --- a/src/libstore/build.cc +++ b/src/libstore/build.cc @@ -2020,7 +2020,10 @@ void DerivationGoal::initChild() createDirs(chrootRootDir + "/dev/pts"); Strings ss; ss.push_back("/dev/full"); - ss.push_back("/dev/kvm"); +#ifdef __linux__ + if (pathExists("/dev/kvm")) + ss.push_back("/dev/kvm"); +#endif ss.push_back("/dev/null"); ss.push_back("/dev/random"); ss.push_back("/dev/tty"); -- cgit 1.4.1
