In the RES (Resident Memory) column, the image carves out its dedicated 2GB or 4GB of RAM, ensuring it has enough room to manage routing tables.
Assign exactly 1024 MB RAM and 1 vCPU to the node.
This creates the internal communication path that allows the RE to "program" the VFP. 3. Basic Configuration vqfx202r110reqemuqcow2 top
| Issue | Likely Cause | Fix | |-------|--------------|-----| | High %sy in top | KVM paravirtualization missing | Use -cpu host in QEMU | | ksoftirqd high CPU | Too many interrupt requests | Reduce NICs or use virtio | | vQFX hangs on boot | Insufficient RAM | Increase to 6GB | | top shows 100% idle but CLI slow | Disk I/O wait on slow storage | Move QCOW2 to SSD |
Configure the node with at least 4 to 8 network adapters . Set the first interface ( em0 ) for Out-of-Band management, and link the second interface ( em1 ) directly to em1 on your PFE node. Critical Workarounds & Pitfalls 1. The Junos Version Mismatch Bug Guide: Importing Juniper vMX and vQFX into CML2.4 In the RES (Resident Memory) column, the image
The filename refers to a virtual disk image for the Juniper vQFX-10000 Routing Engine (RE). Specifically, it represents Junos OS version 20.2R1.10 , though users have frequently reported that images labeled as 20.2 actually boot into Junos 19.4R1.10 . Understanding vQFX Architecture
This image allows you to build a complete Virtual Extensible LAN (VXLAN) fabric with Ethernet VPN (EVPN) control plane signaling. You can test:
: When downloading the official evaluation image labeled vqfx-20.2R1.10-re-qemu.qcow2 from Juniper, booting the image and typing the show version command reveals that the system reports itself as Junos: 19.4R1.10 limited .
Point the primary master disk ( hda ) to your local copy of vqfx-20.2R1.10-re-qemu.qcow2 .
