What is the difference between KVM and OpenVZ VPS in India?

KVM (Kernel-based Virtual Machine) gives each VPS a fully isolated kernel and dedicated virtualized hardware. You can run any OS, custom kernels, Docker, and game servers. OpenVZ shares the host kernel, which limits what software you can install and makes resource contention worse during host peaks. For production workloads, always choose KVM.

Should I choose Mumbai or Singapore for a KVM VPS in India?

Choose Mumbai if your users are primarily in India — typical RTT from Mumbai to Delhi is 20–35 ms, Bengaluru 15–30 ms. Choose Singapore if you serve Southeast Asia (Malaysia, Indonesia, Thailand) alongside India, where Singapore provides 5–20 ms to SEA and acceptable 30–50 ms to Indian cities.

Do Indian KVM VPS providers include cPanel?

cPanel is usually an optional paid add-on, not included by default. HostStack offers cPanel licensing as an add-on during order or from the client portal. Expect ₹800–1,500/mo extra for a cPanel licence on top of the base VPS price. If you only need to host WordPress or custom apps, you can use Webmin, HestiaCP, or CloudPanel free of charge instead.

What should I check after my KVM VPS is provisioned?

After provisioning: (1) SSH in with the root credentials from your welcome email, (2) run 'apt update && apt upgrade' to apply security patches, (3) check disk performance with 'fio --name=test --rw=randrw --size=512m', (4) verify network speed with 'curl -s https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py | python3', (5) set up UFW firewall, (6) enable fail2ban for SSH, (7) take a snapshot from the control panel before installing any software.

KVM VPS India: pre-purchase checklist 2026

By HostStack Editorial · Updated 28 May 2026 · All posts

Buying a VPS without a checklist leads to three common mistakes: wrong location (high latency to your users), underspecced RAM (swap-thrashing kills performance), and no backup plan before the first deployment. This checklist covers what to verify before clicking Order.

1. Verify it is genuine KVM, not OpenVZ

KVM gives each VPS a fully isolated kernel — you can run Docker, custom kernels, and game servers. OpenVZ shares the host kernel, which restricts what you can install and means CPU contention is worse. Ask the provider or look for "KVM" explicitly on the plan page. All HostStack VPS plans are KVM.

2. Match location to your user geography

Mumbai: 15–40 ms RTT to major Indian cities. Best for consumer apps, WordPress sites, game servers with Indian players, and any product where data residency in India matters.
Singapore: 30–50 ms to India, 5–20 ms to Malaysia/Indonesia/Thailand. Best for APAC SaaS products with mixed Indian and Southeast Asian users.
Europe/US: 130–200 ms to India. Only appropriate if your entire user base is in that region.

Test before you commit: use the HostStack looking glass to run a traceroute from Mumbai to your current location and see actual latency numbers.

3. Confirm storage type: NVMe vs SATA SSD

NVMe SSD delivers 3–5x faster random read/write than SATA SSD. For WordPress with a MySQL database, WooCommerce stores, or anything that writes to disk frequently, NVMe is measurably faster. If the plan page says "SSD" without specifying NVMe, assume SATA. HostStack Ryzen VPS plans specify NVMe explicitly.

4. Check CPU type: Ryzen vs Intel Xeon

AMD Ryzen CPUs (used in HostStack VPS plans) offer significantly higher single-thread performance than older Intel Xeon E5 processors common in budget VPS providers. Single-thread performance matters for PHP page generation, Node.js event loops, and game server tick rates. Check the VPS product page for CPU model or ask support before ordering.

5. Determine if cPanel is included or extra

cPanel on a VPS is typically a paid add-on (₹800–1,500/mo). If you need it for client work or a managed WordPress setup, add it during order. If you are running a single application (Node.js API, Laravel, game server), you do not need cPanel — use a lighter control panel like HestiaCP or CloudPanel for free, or manage via SSH directly.

6. Understand the backup policy before ordering

Vendor snapshots are not a substitute for your own backup discipline. Before ordering, confirm: Does the plan include automated backups? How many days of history? Is it snapshots or full file+DB backups? Regardless of the answer, plan to run your own offsite backup (rsync to a separate server, or rclone to an S3-compatible bucket) from day one.

7. Confirm INR billing and GST invoice availability

If you are a GST-registered Indian business, a VPS billed in USD (DigitalOcean, Vultr, Contabo) means no Indian GST invoice and no input tax credit. HostStack bills in INR and issues GST-compliant invoices. Add your GSTIN during order or from the client portal.

8. Check the refund policy before committing to annual billing

Annual billing saves 20–40% over monthly. But if the VPS performs poorly, you want a refund window. HostStack offers a 30-day money-back guarantee. Confirm the provider's refund policy before paying for 12 months upfront.

9. Plan your Linux distribution choice

For most workloads in 2026: Ubuntu 22.04 LTS (supported until 2027, wide package availability) or Debian 12 (more conservative, slightly lighter). Avoid Ubuntu 20.04 (nearing EOL). For CentOS replacements: AlmaLinux 8/9 or Rocky Linux. Choose a distribution you have experience with — debugging an unfamiliar distro under production pressure is painful.

10. What to do in the first 30 minutes after provisioning

SSH in with root credentials from welcome email
Run: apt update && apt upgrade -y (or dnf update for AlmaLinux)
Install UFW: ufw default deny incoming && ufw allow ssh && ufw enable
Install fail2ban: apt install fail2ban -y && systemctl enable --now fail2ban
Take a snapshot from the HostStack control panel (clean baseline before installing software)
Set up your SSH key and disable password authentication (see our hardening guide)

Frequently asked questions

Should I choose Mumbai or Singapore VPS in India?

Mumbai for Indian users (15–40 ms RTT to major cities). Singapore if you also serve Southeast Asia (Malaysia, Indonesia) at 5–20 ms. See our Mumbai vs Singapore comparison for a full breakdown.

Does a KVM VPS in India include cPanel?

Usually no — cPanel is an optional add-on. On HostStack, add cPanel licensing during order for ₹800–1,500/mo extra. If you only need to host WordPress or a single app, HestiaCP or CloudPanel are free alternatives.
