#hypervisor

Attackers have been caught escaping from virtual machines to take over VMware ESXi hypervisors, proving that VM isolation can fail when advanced exploits hit production systems.

Tempo hari, diminta kampus untuk mindah salah satu server yang dari workstation biasa ke server kampus. Karena pakai infrastruktur nya virtual-machine, walhasil tinggal pindah virtual-harddisk (VHD) settingan ikut, tinggal disesuaikan dikit.

Hari pertama setelah selesai pindah, masih ada kendala bahwa server tidak dapat diakses di jaringan lokal. Walaupun dari hoating sudah diarahkan ke alamat IP public terkait dan di reverse proxy ke alamat IP sesungguhnya. Masalah teratasi keesokan harinya setelah network engineer saya minta untuk tambahkan IP static atau ganti IP DNS (DHCP) dengan public DNS.

Namun sangat disayangkan, catu daya mati di siang hari sesaat saya konfirmasi bahwa jaringan lokal sudah dapat mengakses server dengan domain terkait. Masalah selanjutnya datang, yakni setelah dinyalakan server tidak otomatis mem-booting VM. Namun hal tersebut dapat teratasi karena sudah diantisipasi dengan melakukan setting pada BIOS supaya mainboard dapat menyala sesaat setelah mendapat catu daya.

Tinggal masalah terakhir bahwa dari VM sendiri tidak dapat menjalankan cronjob maupun booting otomatis melalui VBoxManage. Hingga akhirnya jalan terakhir adalah menjadikan action tersebut sebuat service yang berjalan sesaat setelah booting hypervisor selesai.

Dan benar, Hari ini terjadi pemadaman listrik. Setelah pemadaman, hypervisor dan VM booting kembali secara normal.

Baru saja, saya menambahkan auto-mount ke harddisk bawaan servernya. Mungkin besok saat restart server akan dicoba dan dilihat hasilnya.

Fin.

 Of Big Brains and Tiny Devices: Here Comes the Internet of the Body

How does a gifted student in Switzerland in the 1980s apply his talents? On precision mechanics and watchmaking, of course.

But at the time the watch industry was facing a challenging period and its four-century dominance was coming to an end as digital began taking over. This triggered Bruno Michel, a student at University of Zurich, to switch his field from mechanics and electronics to biochemistry where he carried out a PhD.

Eventually, he would come to realize that his previously acquired knowhow wasn’t time wasted as he developed smart robots to reach even more accurate results on a much wider library of genetically engineered enzymes he was studying — completely unheard of at the time.

Thankfully for IBM and for the engineering community, these two experiences triggered his fascination with integrating all kinds of functionality into smaller and smaller highly efficient devices.

Thirty-plus years later Michel, a National Academy of Engineering inductee, now leads an IBM Research team in developing tiny, powerful computing devices – some so small they can eventually be fixed in the ear canal or worn as a sub-millimeter thin patch no more intrusive than a Band-Aid.

These devices are part of an initiative known as the Internet of the Body, which is part of the IBM Frontiers Institute, a collaborative effort bringing together IBM scientists with clients to work side by side on forward thinking science with implications for business and society.

A hypervisor is a key virtualization technology that allows multiple virtual machines (VMs) to run on a single physical server by managing and allocating hardware resources efficiently.

In this guide, you’ll learn what a hypervisor is, how it works, and the difference between Type 1 and Type 2 hypervisors used in cloud computing, data centers, and server environments.

Le monde du jeu vidéo PC est en ébullition. Selon des informations récentes, la quasi-totalité des jeux solo non-VR utilisant la protection Denuvo auraient été contournés ou crackés. FitGirl, célèbre repackeuse, a annoncé que seuls les titres multijoueurs ou en réalité virtuelle résistent encore. Une nouvelle qui remet en question l'efficacité de ce système de DRM pourtant très répandu. Des…

Virtualization is the backbone of today’s IT infrastructure — but choosing between Type-1 (bare-metal) and Type-2 (hosted) hypervisors can be tricky. 🤔

In our latest guide on #HyperHCI, we explore how each hypervisor type works, their pros and cons, and which one suits your needs — whether you’re running enterprise workloads, managing hybrid cloud deployments, or just setting up virtual labs on your system.

You’ll also discover insights into top platforms like VMware ESXi, Nutanix AHV, Microsoft Hyper-V, KVM, and Proxmox VE, as well as desktop-focused ones like VirtualBox and Parallels Desktop.

💡 Learn how these hypervisors integrate with modern HCI (Hyper-Converged Infrastructure) solutions to boost performance, scalability, and flexibility.

If you’re serious about optimizing virtualization, this guide helps you make the right call for your data center or home lab.
