id summary reporter owner description type status component version resolution keywords cc guest host 10113 Solaris 4.1.6+ guest additions corrupt boot archive and entire virtual disk rasta "Running Sol 10 u8 x64 guest VM on a Win7 x64 host with Core i7 980x Gulftown processor. VM has 4096 MB base ram, 4 processors selected, PAE/NX, VT-X, nested paging, 1 display with 32 MB vram, with 3d acceleration enabled. For the past several vbox versions, I have had my boot archive become corrupted when I installed the latest Solaris additions, leading sometimes to complete virtual disk corruption. This is a MAJOR problem. When installing 4.1.6 additions to replace 4.1.4, the disk got corrupted but I was able to fsck my way out of it. I cannot install 4.1.8 Solaris additions no matter what. After installs corrupted my virtual disk 3 times in a row, I went back several snapshots to the state when 4.1.4 additions were installed, but still 4.1.8 install corrupted the disk. I get timeouts and read sector errors with Gen-ATA and vn_rdwr failed with error 0x5. Disk became corrupted. Let me know if you need any further files, info, or documentation." defect new guest additions VirtualBox 4.1.8 Solaris Windows
