cisco waas kvm hypervisor revealed v08.07.10.txt

Disregard XenSource as the hypervisor (only looking at OUI gets you nowhere).. (updated)

Apparently OUI has little relevance.. 00:16:3E is used by KVM/QEMU as well.

Figure 14-3 on the following documentation page: http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/v411/configuration/guide/virtual.html#wp1052098
Screenshots show a virtual interface with the MAC of: 00:16:3E:54:B6:23
and with a quick OUI lookup at:
http://www.wireshark.org/tools/oui-lookup.html

we'll see that 00:16:3E is: Xensource, Inc. (irrelavent, sorry)

- quick note on this.. what is the point of having a standard if everyone is going to canabilize it! I can understand MAC spoofing from a hackers point of view, but just disregarding it from a vendor level makes it even worse.. I was upset when I couldn't copy the existing MAC from a physical NIC to one under VMware, but I understood their point (and rightly so, they did put a switch to allow an override via the .vmx config)

Other notable points:

- virtio is a selectible disk emulation type, used by KVM.
- KVM uses .img file formats and that is discussed as the backup option (file.img)
- kvm.tar.gz exists in WAAS41.bin (not going any further than that)

retrospect time..

- Cisco works with Microsoft to be one of the first vendors to be certified on the new SVVP program.. people shake there heads and say what??

- Cisco announces a new virtual switch designed to run under the new VMware ESX platform based on the Nexus product line running a Linux kernel.

- Cisco releases a new WAAS product with 4.1 allowing for virtual-blades utilizing the open-source KVM hypervisor. (PV drivers yet to be determined.)

So, I would say this is a very smart move for Cisco in the virtualization space.. they have no allegiance to anyone and are able to capitalize from everyone! Great job!

also note that Edouard Bugnion (VP/CTO, of Cisco's Server Access and Virtualization Business Unit) is a co-founder of VMware and also co-founder of Nuova Systems (the company where the Nexus came from).

So expect many more announcements around virtualization while he is on board.

"...couldn't copy the existing MAC from a physical NIC to one under VMware,..."

FYI, Having done hundreds of P2Vs, you run into programs tied to MAC addresses and you can change the MAC in the .vmx as you point out but you also can simply change it from the OS as well-it works just fine.

xenserver update v08.24.08.txt

author: Randy J. Cress date:
ok, while starting to building the new xenapp 4.5 farm (knowing 5.0 is right around the corner) I've decided not to scrap XenServer Enterprise and give the latest beta with NIC bonding and SAN FC multipathing a shot for our XenApp VMs along with Citrix PVS 5.0 (btw, Dell Flexible Computing has updated their download site) http://www.dell.com/flexiblecomputing Right now I don't have a problem saying we'll use XenCenter to manage the XenApp hosts running XenServer since the PVS servers are running in VMware ESX 3.5 along with the rest of the backend infrastructure.. I thought I would be stuck with no room for any shared storage since the SAN is fully carved with vmfs3 volumes and place from a Xen LVM but with Provisioning Server I can just stream the vDisks to the XenApp servers without a need for any hdd being visible to those VMs. On a side note, the VNC-based implementation for the console in XenCenter is not so cool.. it "feels" like VNC versus a guest run...

using vlc to create a web-based vod library v07.18.11.txt

author: Randy J. Cress date:
There are many reasons why you would want to create Video-on-Demand library with a web interface.. training videos, past security recordings, news clips, etc.. My reason was different this weekend.. it is starting to become difficult to weed through all of the DVDs with children's show for my daughter. While she has no problems sorting through the DVDs and picking out a show to watch if we label it correctly, it still is time consuming and over time the discs become worn and damaged. I needed a way to create a video on demand library and have it easy to use for her. Since she can navigate around on the web just fine, I wanted to make it as simple as YouTube for point and click access to her shows. Enter VideoLAN VLC Player/Server Now we can do the following: TV -> DVR -> DVD -> VLC -> RTSP -> PC = Happy Child The quick and dirty approach for serving DVDs over wired/wireless for VOD via the web: Download and install VLC 0.8.6c here . Copy the entire VIDEO...

an outlook for security improvements in 2019 v18.12.24.txt

author: date:
As we wrap up 2018, my news feeds and various email inboxes are littered with security breaches, security vendor hardware, software and training solutions. All citing an infamous undertone of someone that clicked on a bad link ultimately ending in unwanted code execution that led to more code execution and finally data exfiltration. I am taken aback by our current ecosystem of general purpose operating systems and their bloated sense of "purpose".  When is the last time you purchased multi-layer security solutions for your best of breed gaming platforms in your home network environment?  How often do you bludgeon your children's minds with security awareness training when downloading skins, avatars, games and expansion packs from the respective console gaming platforms online stores?  Do you recognize the computational power, network connectivity and deeply connected devices in your most personal home networks linked to video cameras, door locks and vast array of se...
