The three sandbox QEMU guests each run with `-smp 8`, demanding 24 vCPU in total. On the 24-vCPU runner that is a 1:1 CPU commit with no host headroom for QEMU's emulation/IO threads, vhost-net, the host NAT every guest image pull traverses, containerd and the kernel. Under the peak concurrency of "Install Cozystack" the guests lose cycles to CPU steal, so in-guest readiness/liveness probes miss their deadlines and a HelmRelease intermittently flips InProgress -> Failed with dependents cascading to DependencyNotReady — on a different component each run, the signature of resource thrash rather than a product bug. Move the job to the 32-vCPU / 128 GiB runner class. Guest sizing is unchanged (24 vCPU / 72 GiB), so the install does not slow down, while the host keeps 8 vCPU and 56 GiB of headroom that absorbs the emulation and network overhead the probes were starving against.
